[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.
