__CONCAT

[Robert Millan <rmh@aybabtu.com>]

Hi,

It seems the problems that prevent libfreebsd from being rebuilt (or built for
first time in amd64), boil down to nested __CONCAT usage in elf headers:

#define __CONCAT(x,y) x ## y
int __CONCAT(__CONCAT(a,b),c);

$ gcc -E test.c
[...]
int __CONCAT(a,b)c;

Anyone has an idea on why gcc only expands __CONCAT once?
