This directory contains code for building a compiler for the
32-bit ESA/390 architecture.  It supports three different styles 
of assembly:

-- MVS for use with the HLASM assembler
-- Open Edition (USS Unix System Services) 
-- ELF/Linux for use with the binutils/gas GNU assembler.


Cross-compiling Hints
---------------------
When building a cross-compiler on AIX, set the environment variable CC
and be sure to set the -ma and -qcpluscmt flags; i.e.

   export CC="cc -ma -qcpluscmt"

do this *before* running configure, e.g.

   configure --target=i370-ibm-linux --prefix=/where/to/install/usr

The Objective-C and FORTRAN front ends don't build.  To avoid looking at
errors, do only 

   make LANGUAGES=c


OpenEdition Hints
-----------------
The shell script "install" is handy for users of OpenEdition.
