This directory contains the GNU front-end for the Chill language,contributed by Cygnus Solutions.Chill is the "CCITT High-Level Language", where CCITT is the oldname for what is now ITU, the International Telecommunications Union.It is is language in the Modula2 family, and targets many of thesame applications as Ada (especially large embedded systems).Chill was never used much in the United States, but is stillbeing used in Europe, Brazil, Korea, and other places.Chill has been standardized by a series of reports/standards.The GNU implementation mostly follows the 1988 version ofthe language, with some backwards compatibility options forthe 1984 version, and some other extensions.  However, itdoes not implement all of the features of any standard.The most recent standard is Z.200 (11/93), available fromhttp://www.itu.int/itudoc/itu-t/rec/z.html.The GNU Chill implementation is not being actively developed.Cygnus has one customer we are maintaining Chill for,but we are not planning on putting major work into Chill.This Net release is for educational purposes (as an exampleof a different Gcc front-end), and for those who find it useful.It is an unsupported hacker release.  Bug reports withoutpatches are likely to get ignored.  Questions may get answered orignored depending on our mood!  If you want to try your luck,you can send a note to David Brolley <brolley@cygnus.com> orPer Bothner <bothner@cygnus.com>.One known problem is that we only support native builds of GNU Chill.If you need a cross-compiler, you will find various problems,including the directory structure, and the setjmp-based exceptionhandling mechanism.The Chill run-time system is in the runtime sub-directory.Notice rts.c contains a poor main's implementation of Chill"processes" (threads).  It is not added to libchill.a.We only use it for testing.  (Our customer uses a differentimplementation for production work.)The GNU Chill implementation was primarily written byPer Bothner, along with Bill Cox, Wilfried Moser, MichaelTiemann, and David Brolley.
