User-agent: Gnus/5.11 (Gnus v5.11) Emacs/22.2 (gnu/linux)


here are the latest changes.  Summary fixes:

   -  argument ordering bug fixed.
   -  explicitly use bash when necessary.
   -  macport section added and later improved.
   -  bug fixes to variant record checking.
   -  SMathLib0.{def,mod} new files.
   -  documentation updated and web pages updated.
   -  ISO M2 language now implemented.

If you use a mac then you might be interested in the macports section.
At the end of this section there is a script which will automatically
pull down the latest gm2 from a cvs tarball, build the compiler, run
gm2.paranoid and all the regression tests.


   *  added SMathLib0.def to list of library
   * gm2.texi:  added build log for macports description.
   * gm2-compiler/M2CaseList.mod:  only test case ranges if
     the high field is used, otherwise test equality.  Check
     that case types are also known and their maximum and
     minimum values.
   * gm2-compiler/SymbolTable.mod:  only place record fields
     into the Record.LocalSymbol tree if the name is not NulName.
   * gm2-libs/SMathLib0.mod:  many fixes to SMathLib0 using the
     correct libm function name expf, sqrtf etc.
   * gm2-libs-iso/Processes.def:  tidied up comment formatting.
   * gm2/gm2.texi:  improved the building under macports section.

   * gm2/www/  updated to reflect recent changes.
     Removed older build platforms.

   * gm2/gm2.texi:  added macport section.  Also updated
     state of gm2 within the documentation.  The languages
     are complete, libraries are incomplete.

   * gm2/  added dependency on
     $(objdir)/gm2/gm2-libs for gm2/gm2-libs/gm2-libs-host.h.
     Added dependencies on cc1gm2$(exeext) when creating
     SYSTEM.def.  Explicitly invoke bash to run bash scripts
     rather than assume that the developers SHELL is bash.

   * gm2/gm2spec.c:  fixed an off by one bug when scanning
     arguments.  This manifested itself as a linking bug
     (as reported by John O Goyo <address@hidden>)
     when arguments were presented in a different order.
     '-o' skipped one to many arguments.
