Log Message:
more updates for modern compilers / C versions.

ar_scan() takes a "void *" for both it's last arg, and the func's
last arg.  adjust some callbacks to cope without casts.

in configure, use return instead of exit(3) to avoid wanting stdlib.h.

if wanting a void signal retsigtype, use the right function (XXX, maybe
just give up and remove all this now in 2026.)

remove checks for __GNU_LIBRARY__ before including stdlib.h or unistd.h,
so that valid prototypes are enabled, and remove incomplete prototypes
for them from these sources (eg, getenv(), getopt(), errno.)

avoid using bsd_signal entirely as a name, by defining it to
gmake_bsd_signal() after including signal.h.

fixes builds for me on netbsd using GCC 12, 14, and 15.
