Basically, all platforms with a non-GCC compiler will need this patch. Think of Solaris cc, HP-UX cc, native Windows with MSVC... > As I mentioned, this is really a gnulib > issue and thus I'm reporting it there. No, it is not an issue in gnulib. In gnulib, the module 'regex' depends on the module 'builtin-expect' (with the appropriate condition), and this latter module guarantees that __builtin_expect is defined also on non-GCC compilers. The issue is with gawk's use of gnulib: it does not use gnulib-tool and instead relies on (error-prone) manual sync from source files from gnulib. Bruno
