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.
