For anyone interested in Modula-2 as a potential replacement for C as a systems language, there is a small but hopefully growing revival of the language occurring on the Gnu Modula-2 mailing list and (especially) on comp.lang.modula2 . Right now there is a call on the newsgroup for testers of the Modula-2 to C (M2C) compiler.  This is part of a larger effort for the Modula-2 Revision 2010 (M2 R10) language definition and implementation by Benjamin Kowarsch and Rick Sutcliffe.
