Using the -g flag to gcc, the following program compiles but fails to link.
The error message is

gcc -g test.c
/cygdrive/c/TEMP/ccJVVXiI.o(.stab+0x1c4): In function `test':
/support/crbrb.c:11: undefined reference to `LC0'
collect2: ld returned 1 exit status

Contents of test.c is

int main(){
    return 0;
}
void test(double *b)
{
    register double a = 0.0;
    int k;
    for (k = 0; k < 1; k++) {
        *b = a;
    }
}


Removing the 'register' keywork or switching off the debug option 'fixes'
the problem. This bug seems specific to cygwin. gcc 3.2 on [intel] linux
works ok.

Version information: gcc version 3.2 20020927 (prerelease)
