macro expansion producing 'defined' has undefined behavior [-Wexpansion-to-defined] with Apple clang 17.0.0 #33
Description
./../m4ri/mzd.h:1002:5: warning: macro expansion producing 'defined' has undefined behavior [-Wexpansion-to-defined]
1002 | #if __M4RI_HAVE_SSE2
| ^
./../m4ri/m4ri_config.h:7:28: note: expanded from macro '__M4RI_HAVE_SSE2'
7 | #define __M4RI_HAVE_SSE2 (defined(__SSE2__) && __SSE2__)
| ^
the latter #define should be using if/then/else instead.
I'll fix it and do a PR
