            Bug ID: 280715
           Summary: math/py-numpy: remove clang error condition in
                    distutils check
           Product: Ports & Packages
           Version: Latest
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: Individual Port(s)
          Assignee: python@FreeBSD.org
          Reporter: dim@FreeBSD.org
             Flags: maintainer-feedback?(python@FreeBSD.org)
          Assignee: python@FreeBSD.org

numpy has a C source file in their distutils checks, which is supposed
to check for AVX512FP16, but for apparently historical reasons, it has:

    /* clang has a bug regarding our spr coode, see gh-23730. */
    #if __clang__
    #error
    #endif

Since clang 19 now supports the -mavx512fp16 flag, other ports such as
science/py-scipy (which depend on numpy) then bomb out in their
configure scripts with:

pr.c:20:2:

          |  ^
    1 error generated.

I have tried clang 15 through 19 on cpu_avx512_spr.c with the #error
removed, and none of them crashed or otherwise got an error. So I think
we should simply remove the whole #if / #endif part.

Also bump the portrevision, to force dependencies to configure against
the new cpu_avx512_spr.c file.
