With setting 

WITHOUT_SYSTEM_COMPILER=YES
WITHOUT_SYSTEM_LINKER=YES

in CONF_BUILD and CONF_WORLD and WITHOUT_CROSS_COMPILER=YES commented out (not building/not
cross compile?) and a fresh and clean start of the build, I run into

[...]
ld: error: args.o: Opaque pointers are only supported in -opaque-pointers mode (Producer:
'LLVM15.0.7' Reader: 'LLVM 14.0.5') cc: error: linker command failed with exit code 1 (use -v
to see invocation) *** [gh-bc] Error code 1
[...]

That seems to be the issue mostly discussed herein regarding LLVM14 and LLVM15.

Having set

WITHOUT_CROSS_COMPILER=YES
WITHOUT_SYSTEM_COMPILER=YES
WITHOUT_SYSTEM_LINKER=YES
WITHOUT_MODULES=an


in both CONF_BUILD and CONF_WORLD (I do so because I do not know which one is really affecting
the build), I receive the reported compiling error problem in if_an.c.

Setting WITHOUT_MODULES=an in both CONF_BUILD and CONF_WORLD (nanoBSD!) doesn't seem to have
any effect.

Regardfs,

oh
