/*
 * minicpp
 * ======================
 * 
 * Mozilla requires only a few libstdc++ functions.  Minicpp
 * is a simple stub that provides these functions allowing 
 * some application using Mozilla not to include libstdc++
 * with their distribution.
 * 
 * To build minicpp, on linux:
 * 
 * gcc -shared -o libminicpp.so -fPIC minicpp.cpp
 * 
 * Results may vary.
