C compiler toolchain and library improvements for HelenOS

by Jiří Zárevúcky for HelenOS group at Department of Distributed and Dependable Systems, Charles University in Prague

At the moment, the only way to build software for use in HelenOS is to cross-compile it as part of the operating system's source tree from another operating system. The intent of this project, should it be accepted, is to provide a functional C compiler for use natively within HelenOS, as well as to improve the native C library and to provide a compatibility layer for legacy POSIX software.
