[vox-tech] is this a glibc bug?



hola,


#include <stdio.h>
#include <math.h>

int main(void)
{
   int y1 = 9;
   printf("%d\n", y1);
   return 0;
}

p@satan% gcc -Wshadow blah.c  -lm
blah.c: In function `main':
blah.c:6: warning: declaration of `y1' shadows global declaration


the problem is that there's a global variable named "y1" in
/usr/include/bits/mathcalls.h which gets included by math.h.

so GNU glibc has ruined the variable name "y1".

would this be considered a glibc bug?   if they're going to ruin a
variable name, they should at least document it like errno, _ and __
type variables.
