Package: emacs, ada-mode

--

I have updated build.sh a bit:

  * if build.sh called with extra options then these options are passed to
gprbuild.
    (to allow using more CPU's, passing other gnat options, ... without
modifying the *.gpr files.)
  * Not using ' $GPR_PROJECT_PATH' to wisi directory, as GPR_PROJECT_PATH
is used by gprbuild. (and can point to own compiled gnatcoll_xref and
others)
  * Allow calling build.sh multiple times
           - first call gprclean, to clean project
           - not removing ' ada_lr1_parse_table.txt.gz'

If you agree on these changes, can someone apply this patch to ada-mode?

Thanks,

Koen
