Yes, I have the same experiences. Also error checking is improved
again.

Hmmm, although I'm doing a lot of file scanning/parsing right now
I haven't run into this (yet?).

I hardly dare to ask, but are you sure it's not a file format
translation
(unix (LF) to DOS (LF/CR) problem ? Both GNAT and DJGPP have
options controlling the translation.

That is really odd.You are not using djgpp 2.01 ?

Note that *DOS error 8* (what is what in djgpp the signal number 
means) is 'out of memory'.

In 3.05 the 'strip' utility was automatically run when building a
executable, this
has been left out of 3.07. To get back to the 3.05 filesizes use:

exe2coff file.exe
strip --strip-all file
coff2exe file
del file

By setting the proper file format options, see GNAT and DJGPP docs.

BTW although we should be glad ACT has provided us yet again with
a new version of GNAT/DOS, it would have been even nicer if:

a) DJGPP v2.01 was used as a platform, the incompatibilities are a
    major PITA;

b) GNAT would use the DJGPP Long Filename Support when running
    in a Win95 DOS box.
