from c99 appendix F p 445
F.4 Floating to integer conversion
[#1] If the floating value is infinite or NaN or if the
integral part of the floating value exceeds the range of the
integer type, then the invalid exception is raised and the
resulting value is unspecified.
this indicates that the bug is in the test
here is a modified test with sol11.sun4 results
could someone run it on sol11.i386

#define _ISOC99_SOURCE 1

int main(int argc, char** argv)
{

long long s;
unsigned long long u;
f = INFINITY;
s = f;
u = f;
printf("%4Lf %20lld 0x%016llx %20llu 0x%016llx\n", f, s, s, u, u);
f = -f;
s = f;
u = f;
printf("%4Lf %20lld 0x%016llx %20llu 0x%016llx\n", f, s, s, u, u);
