Ah. On 10.5, I get
checking for random... no
And from config.log the only references to "random" (in a case
insensitive search) are:
configure:6963: checking for random
configure:6991: gcc -o conftest.dSYM -g -O2 -I/sw2/include -L/sw2/lib
conftest.c 1>&5
error: Not a directory - unable to create 'conftest.dSYM/Contents'
bundle directory.
configure: failed program was:
#line 6968 "configure"
#include "confdefs.h"
/* System header to define __stub macros and hopefully few prototypes,
which can conflict with char random(); below. */
#include <assert.h>
/* Override any gcc2 internal prototype to avoid an error. */
/* We use char because int might match the return type of a gcc2
builtin and then its argument prototype would still apply. */
char random();
int main() {
/* The GNU C library defines this for functions which it implements
to always fail with ENOSYS. Some functions are actually named
something starting with __ and the normal name is an alias. */
#if defined (__stub_random) || defined (__stub___random)
choke me
#else
random();
