exception handling. There are now two layers an error or warning goes
through before it hits the user: first an error is logged via
yasm_error_set() (or yasm_warn_set() for a warning). Only one error may
be set, whereas multiple warnings can be set (yasm_warn_set maintains a
linked list). Then, calling yasm_errwarn_propagate() propagates any error
and/or warning(s) to an errwarns structure and associates the
errors/warnings with a line number at that time; this call also clears the
pending errors/warnings and allows new ones to be set. The propagate
function can safely be called when there are no pending error/warnings.
In addition, there are some helper errwarn functions that allow clearing of
an error/warning without propagating, getting it separately, etc.
Still yet to be done: changing most/all uses of yasm_internal_error() into
yasm_error_set(YASM_ERROR_ASSERTION).
The main advantage this change has is making libyasm functions feel much
more library like, and separating the user code line numbers from the inner
function error handling (e.g. intnum create functions only needed the line
number to trigger errors; this is no longer required).
The set/propagate/etc functions use global data structures to avoid passing
around a pointer to every function. This would need to be made thread-local
data in a threaded app. Errwarns containers (that keep associated line
numbers) are no longer global, so multiple source streams can be processed
separately with no conflict (at least if there's only a single thread of
execution).

The m4_ifvaln() call doesn't seem to serve a purpose and generated bad shell
script code (trying to actually run a header file).
_STDINT_HEADER_INTPTR ifdef shouldn't wrap INTMAX_T check.

string length can change. This was breaking symbol name lookups when the
filename was changed (e.g. for dwarf2).

yasm_intnum_get_sized().
* intnum.h (yasm_intnum_create_sized): Prototype.
* yasm.pyx: Bring in _PyLong_From/AsByteArray functions.
* intnum.pyx: Use yasm_intnum_create_sized(), etc to implement full 128-bit
number handling.
* intnum.c (yasm_intnum_get_str): Return strings in hex rather than in
decimal.

we shouldn't need to remove the build directory. Not removing it speeds up
the build considerably (we don't have to rebuild all of the Python bindings
just because the Makefile changed, for example).

decreases bloat and more importantly makes it possible to use >32-bit values
in the preprocessor.
This has NOT been heavily tested, so there may easily be bugs. I've not yet
decided whether to merge this to 0.5.0 final for this reason.
Inspired by: Jason Chen <jchen@centtech.com> patches to use "long long"
rather than "long" in the preprocessor to enable >32-bit values.
* coretype.h (yasm_op): Add XNOR, LXOR, LXNOR, LNOR.
* intnum.c (yasm_intnum_calc): Calculate the above.
* expr.c (expr_is_constant, expr_can_destroy_int_left)
(expr_can_destroy_int_right, ...): Actually handle logical operations,
including the new ones.
* intnum.c (yasm_intnum_get_str): New; gets a signed decimal string
representation of an intnum.
* intnum.h (yasm_intnum_get_str): Prototype.
* nasmlib.c (nasm_strcat): Change parameters to const.
* nasmlib.h (nasm_strcat): Update prototype.
* nasm-preproc.c (nasm_preproc_input): Close a memory leak.
* nasm.h: Clean out a lot of cruft we don't use.
(tokenval): Change t_integer and t_inttwo to yasm_intnums.
(evalfunc): Remove fwref and hints parameters (cleanup), change return value
to yasm_expr.
* nasm-eval.c: Massively rewrite to just call appropriate yasm_expr creation
functions rather than calculating the value here. Overall recursive descent
parsing structure is unchanged.
* nasmlib.c: Remove a lot of now-unused functions.
(nasm_readnum): Use yasm_intnum functions and return that.
(nasm_readstrnum): Likewise.
* nasmlib.h: Update prototypes.
* nasm-pp.c: Change to use intnum/expr as necessary.
* nasm-preproc.c (nasm_preproc_destroy): Don't call nasm_eval_cleanup,
it's been deleted.
* nasmpp-bigint.asm: New test for >32-bit preproc values.
* ifcritical-err.errwarn: The new code doesn't generate a duplicate warning.

tokenizers. Signed chars >127 are negative, and thus aren't caught by the
[\000-\377] range.
* gas-parser.h (YYCTYPE): Change to unsigned char.
* gas-bison.y, gas-token.re: Cast as necessary to char.
* nasm-parser.h, nasm-bison.y, nasm-token.re: Likewise.
* lc3bid.re: Likewise.

gcc --version; this is just extra information. POSIX needs -n 1 instead of
-1; instead of dealing with this, just disable this function.

(which is used for the tar.gz name). Also clean up Mkfiles/config.h
* configure.ac: Change autoconf version back to HEAD, add new PACKAGE_INTVER
and PACKAGE_BUILD config.h defines.
* cv-symline.c, yasm.c: Use PACKAGE_INTVER and PACKAGE_BUILD instead of
PACKAGE_STRING.
* genversion.c: Likewise.
* Mkfiles: Clean up and add PACKAGE_INTVER and PACKAGE_BUILD.

current major and minor version but with subminor version = 99. All releases
and snapshots will have a build version of the current svn version. Version
information is put into predefined macros in the NASM preproc:
__YASM_MAJOR__, __YASM_MINOR__, __YASM_SUBMINOR__, __YASM_BUILD__,
__YASM_VERSION_ID__, __YASM_VER__.
__YASM_VER__ does not have the build version as part of the string, and
__YASM_VERSION_ID__ does not incorporate the build version.
If the build version is "HEAD" (or other non-numeric), __YASM_BUILD__ is
set to 0.
* configure.ac: Set version to 0.4.99.HEAD for trunk.
* genversion.c: Generate version.mac for the NASM preproc version macros.
* Makefile.inc: Hook into build.
svn path=/trunk/yasm/; revision=1464
* genstring.c: Generate string array from source file.
* Makefile.am: Build genstring.
* Makefile.inc: Use genstring to create license.c from COPYING.
* yasm.c: Include license.c and use it for new --license option. Shorten
--version option to just displaying version, compile date, and very short
copyright message.
