# Build script for motif / OpenMotif 2.3.8 (autotools, Template A).
# Older codebase - config.sub/libtool/__EXTENSIONS__ gotchas expected.
# CORRECTION (2026-07-23): motif's own configure.ac only references its
# in-tree bitmaps/Makefile, but lib/Xm/I18List.c has a *hardcoded*
# `#include <X11/bitmaps/gray>` - a real X.Org bitmap from the standalone
# xbitmaps package, NOT one of motif's own bitmaps/. Needs base/xbitmaps
# built+installed to $PREFIX/include first (see zports base/xbitmaps).

# GOTCHA: lib/Xm/Xmfuncs.h #defines bcopy/bzero/bcmp as function-like
# macros (for pre-ANSI systems) BEFORE illumos's X11/Xos.h later does its
# own (normally-safe, guarded) `#include <strings.h>`. Since strings.h
# hasn't been seen yet at that point, its `extern int bcmp(const void *,
# ...)` etc. prototypes get macro-substituted into invalid syntax
# ("expected declaration specifiers ... before '(' token"). Fixed by
# patching Xmfuncs.h to pull in <strings.h> itself before defining the
# macros, so strings.h's own include guard makes Xos.h's later include a
# no-op. See patches/0001-xmfuncs-strings-h-macro-mangling.patch.

# `const char **` prototype instead, and the explicit (char **) cast in the
# old motif source becomes an incompatible-pointer-type error under GCC 14's
# now-stricter default). Define _XPG6 to select the signature the existing
# cast already expects, rather than patching upstream source.
