[BUG] gcc-3.4.5-20050531 (i386): __FUNCTION__ as a part of the printf's format argument

Such an example can't be compiled:


#include <stdio.h>

void x()
{
    printf(__FUNCTION__ "\n");
}


$ gcc printf.c -o fprintf
printf.c: In function `x':
printf.c:5: error: syntax error before string constant


Then, the problem is not printf-specific and is not depend of
<stdio.h>.  The next example gives the same error:


void y(const char *f, ...);
void z()
{
    y(__FUNCTION__ "\n");
}


If some args are present in the ellipsis section (i.e. y(__FUNCTION__
": %s\n", "xxx")), the problem doesn't vanish.  And, if __FILE__ is
used instead of __FUNCTION__, the problem is absent.
