GNU C/C++ compiler builds the same w/o complaining.

Compiled the GIF library from the https://sourceforge.net/p/giflib/code/ci/master/tree/ and build finished as there is no mention of the extern void *reallocarray(void *optr, size_t nmemb, size_t size) anymore. So no conflict.

Clearly the problem in the old giflib-devel-5.1.4-3.el8.x86_64.

As usual. Closing.
