conditional compilation with gnatmake
Back in July, there was a thread about conditional compilation:
http://groups.google.com/group/comp.lang.ada/browse_thread/thread/634259facc42df7a/2af882a659c4e1f6?lnk=st&q=&rnum=1&hl=en#2af882a659c4e1f6
I said at one point:
In GNAT, the use of preprocessed files is not so transparent,
because gnatmake does not know how to run the preprocessor.
However, I was browsing the GNAT 5.04a user's guide recently, and
discovered that gnatmake does, in fact, know how (and when) to run the
gnatprep preprocessor.
GNAT-GPL-2006 also has this feature.
The "super-secret documentation" strikes again :).
