pkgs/development/libraries/pcre: fixed build on Darwin
The gcc version used on Darwin fails to compile the C++ interface to the PCRE library when optimizations are enabled. Building C++ code with -O0 remedies the problem. This is unsatisfactory, though, because the resulting library is likely to perform more poorly than it would if built with -O2 or -O3. svn path=/nixpkgs/trunk/; revision=24072
