GCC used to stand for the GNU C Compiler, but since the compiler +supports several other languages aside from C, it now stands for the +GNU Compiler Collection.

A list of successful builds is updated +as new information becomes available.

The GCC developers would like to thank the numerous people that have +contributed new features, improvements, bug fixes, and other changes as +well as test results to GCC. +This amazing +group of volunteers is what makes GCC successful.
