Re: Ada compiler

I run RH 9 where I use two Ada development accounts, one for 3.15p
development and one for what came with the system, i.e., gcc-3.2.3.

Ditto, this is what I do, never had any problems with it.

I compile the exact same code from the 3.15p baseline under gcc 3.2.3 and it
compiles and runs fine--I've noticed no differences in execution. (And I
admit being a bit surprised about my lack of problems given the reports of
3.2 problems.) The only compilation difference is 3.2.3 warnings that the
pragma "Unreferenced" is unknown.

My software, DTraq (www.dtraq.com/dtraq.html), heavily uses tasking and the
GUI is implemented with GtkAda, and so far--knock on wood--my experience
with the output of the two compilers has been one of identical execution.
(DTraq also uses ASIS, which isn't available for 3.2.3, so I can't compile
that portion of DTraq of course, but the output of the 3.15p version of the
executable that employs ASIS is usable by the remainder of the tool, so
everything ends up working just fine.)
