acinclude.m4: fix configure tests broken with Clang 16 (implicit function declarations)
Clang 16 will make -Wimplicit-int and -Wimplicit-function-declaration
errors by default which can, in addition to other things, lead to
some configure tests silently failing/returning the wrong result.

or the (new) c-std-porting mailing list [3].
