Description: The GNU (egcs) C compiler.
This is the egcs version of the GNU C compiler, a fairly portable
optimizing compiler which supports multiple languages. This package
includes support for C. This package is _not_ the default c compiler
on this architecture: for that, check out the gcc package.
