New features of old-dejagnu.exp

[Alexandre Oliva]

Hi!

Mike Stump reminded me that I should have made more alard :-) about
the new features I have introduced in old-dejagnu.exp, used for the C++
testsuite.  The new features allow:

- separate steps of compilation and linking, so that -frepo can be
tested.  The magic is to add:

// Build then link:

to the source file.  You'll probably also want:

// Special g++ Options: -frepo


- Allow several sources to be compiled at a time, so that linker
problems and cross-translation-unit bugs can be detected.  The magic
is to add:

// Additional sources: foo.cc bar.cc

to the main (.C) testcase.  I admit it is a very dirty hack, and it
should probably be reimplemented in the future so as to allow // ERROR 
directives in the additional sources and such.

Enjoy!
