The config.log wasn't very useful but I hacked configure to not send
compile/run errors to /dev/null and got this:
checking whether long long int is 64 bits... ./conftest: relocation
error: ./conftest: undefined symbol: __muldi3
Apparrently something is whacked when running from configure. I can take
the exact code (minus the confdefs.h) and run it from the command-line
and it compiles, links, and executes fine (returns 0).
[] config.log:
configure:7610: checking whether long long int is 64 bits
configure:7648: gcc -o conftest -O2 conftest.c -lssl -lcrypto -lz
-lcrypt -lresolv -lnsl -ldl -lm 1>&5
configure: failed program was:
#line 7619 "configure"
#include "confdefs.h"
typedef long long int int64;
/*
* These are globals to discourage the compiler from folding all the
* arithmetic tests down to compile-time constants.
*/
int64 a = 20000001;
int64 b = 40000005;
int does_int64_work()
{
int64 c,d;
if (sizeof(int64) != 8)
return 0; /* definitely not the right size */
/* Do perfunctory checks to see if 64-bit arithmetic seems to work */
c = a * b;
d = (c + b) / b;
if (d != a+1)
return 0;
return 1;
}
main() {
exit(! does_int64_work());
}
