Thanks. That doesn't look like a positive number (which is what I feared)
There shouldn't be a problem *as long as* only that warning from gcc is
broken. if the warning is non broken because gcc is actually treating
-2147483648 as a large positive number then things are going to go wrong.
[if it is, I guess we con gcc by making sure I32_MIN ends up by being
defined as -2147483647-1]
Please could you send the output of this revised test program:
#include "EXTERN.h"
#include "perl.h"
int main (void) {
double a = I32_MIN;
char buffer[256];
puts ("I32_MIN='"STRINGIFY(I32_MIN)"'");
sprintf (buffer, "I32_MIN=%g", a);
puts (buffer);
return 0;
}
[It's convoluted as printf is #defined as PerlIO, but puts and sprintf don't
sem to be affected]
I get
./testit
I32_MIN='(-2147483647-1)'
I32_MIN=-2.14748e+09
