Subject: Avoid compiler warnings in comp.c on MS-Windows
X-Git-Tag: emacs-28.0.90~951^2
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=6b631f490adf66d94a3f566215e7efb7b068a128;p=emacs.git

Avoid compiler warnings in comp.c on MS-Windows

* src/comp.c (DEF_DLL_FN, init_gccjit_functions): Don't load and
don't define functions/macros if libgccjit doesn't have them, to
avoid compiler warnings.
