GNU Pascal
Pascal computer language compiler.

GNU Pascal is the Pascal language compiler of Project GNU. It is a 32/64 bit compiler that is linked against the GCC backend and will be integrated in to GCC in the long run. It runs on all operating systems compatible with GCC, and can act as a native or a cross compiler between those systems. It implements ISO Pascal, Borland Pascal 7.0, and parts of other Pascal standards or de-facto standards.
