* src/pshinter/pshalgo1.c, src/pshinter/pshalog2.c,
src/pshinter/pshglob.c, src/pshinter/pshrec.c,
src/autohint/ahmodule.c: removing compiler warnings with
DEBUG_HINTER defined (only used in development builds anyway)
* src/pshinter/pshalgo3.h, src/pshinter/pshalgo3.c: removing
compiler warnings, and improving the support of local extrema
and stem edge points
* test/gview.c: small updates to the hinting debugger
* Jamfile: small updates
2002-08-18 Arkadiusz Miskiewicz <misiek@pld.ORG.PL>
* builds/unix/install.mk (install, uninstall): Add $(DESTDIR) to
