CVS commit: src/tests/lib/libm

[Taylor R Campbell]

Module Name:    src
Committed By:   riastradh
Date:           Mon May  6 18:35:59 UTC 2024

Modified Files:
        src/tests/lib/libm: t_modf.c

Log Message:
tests/lib/libm/t_modf: Use isinf(INFINITY) to detect inf support.

Apparently VAX defines the INFINITY macro even though it's not
actually an infinity and isinf returns zero for it.
