Hello,
I just upgraded to OpenBSD 7.9 (Congratulations for the release!) and
with it latest gcc 15.2
I want to compile ArcticFox with gcc and use:
export CC="egcc -march=pentium-m -Wno-implicit-int"
export CXX="eg++ -march=pentium-m"
export LDFLAGS="-Wl,-zwxneeded"
However, compilation fails with:
1:37.81 In file included from
/usr/local/lib/gcc/i386-unknown-openbsd/15.2.0/include/immintrin.h:27,

From what I searched, cmpccxaddintrin.h is a clang flag and I have it:
$ find / -name cmpccxaddintrin.h
/usr/lib/clang/19/include/cmpccxaddintrin.h
Is egcc including in its internal headers a clang header and fails to
find it on usage. A gcc packaging error or do I miss something?
It used to work in gcc 7.7 (didn't try compiling on 7.8, although I did
a clean 7.7->7.8->7.9 ugrade)
For curiosity, I will try a full clang compile, but gcc should work I guess.
