Which locale do you use ?
LC_CTYPE is set to en_US and LC_LANG/LC_ALL are unset. So I assume 'en_US'. > 2. Starting with Solaris 11/B72 there is libast.so.1 which comes with an > own set of pattern matching functions.

So I tried to build ast-ast.2007-06-28.tgz, but that fails under Solaris (must admit, that I never understood the mamake magic to be able to troubleshoot). Anyway, it builts on Linux and thus I've a number for the same test: Linux (libast) 24.269u 0.160s 0:24.49 99.7% (gcc -O5 regex.c -L /export/scratch/build/ast/arch/linux.i386/lib -last) So I guess, it wouldn't be an improvement on Solaris, too.
