Libtool's libtool.m4 contains a number of tests similar to
AC_CHECK_LIB(m, main, LIBM="$LIBM -lm")
I assume that this is intended to simply verify that the library
exists by linking against it, but not actually testing for a function.
The test program produced looks like:
int
main ()
{
main ();
;
return 0;
}
Unfortunately, I am informed that both SUN's CC and SGI's CC warn
about the recursive call to main(), and the tests fail. It seems that
this is a poor shorthand to use. A more reliable means would be to
test a function which is known to exist in the library being tested.
