[Bug c/16286] New: Compile errors on altivec ops after #undef vector

[paulus at samba dot org]

The Altivec PIM says that programs may #undef vector and/or pixel if desired.
However, doing that with the current <altivec.h> leads to compile errors.
This test program:

#include <altivec.h>
#undef vector

void test(void)
{
        __vector unsigned int a, b;
        a = vec_and(a, b);
}

gives the error:

vb2.c: In function `test':
vb2.c:8: error: parse error before "vector"

when compiled with gcc -c -maltivec.  If I take out the #undef vector then
the error doesn't occur.

Ben, are you going to fix 'pixel' and 'bool' as well?  It should be possible to
#undef those identifiers.

Yes, I have a patch and a revised test case that I will submit shortly.
Thanks for reminding me.
