Re: gnat for DOS

iAl asked

"There is a note in the gnat archive with the DOS version that says
that the gnat make is broken under DOS.  Does this mean that gnat is
not currently useful to develop programs that will run under DOS, or
is there any way around this problem?  Are there any ideas about of
when the expected remedy to this difficulty will be available?"

It is perfectly possible to use GNAT without an automatic make
facility, though it is certainly more convenient to have it available.
The reason that gnatmake does not work with the current DOS version
is that there is not enough low memory space with DJGPP version 1.

Ada Core Technologies will shortly be releasing a new DOS version, which
will also be available in Mike Feldman
's EZLoad packaging that fixes this problem (by using DJGPP 2), and also
fully implements tasking.

P.S. Even with the new version, you are well advised to move to a real
32 bit operating system (OS/2, NT. Solaris 86, Linux, FreeBSD, NetBSD,
Nextstep) to do any serious Ada development on a PC. Of these at least
OS/2, Linux and NT support tasking fully.
