My results with configure scripts have been it either works or it
doesn't.  When it doesn't, generally the code is using something
the DJGPP doesn't support.  When it does, the app compiles for
DJGPP.  I.e., if the configure script doesn't work, it's a strong
indication it won't compile without some work.

MinGW in DOS with HX...  Interesting.  How many functions are in
MSVCRT?  I.e., would it be easy to port MinGW to DOS?

My first question to Louis is how could MinGW rebuild DJGPP
without POSIX support?  CygWin has POSIX support.

My second question is to Louis is why you're rebuilding version
2.04?  2.04 doesn't work as well with DOS as 2.03.  There are some
definate bugs with it, at least with MS-DOS v7.10.  IIRC, 2.04 is
designed to work better in a Windows XP console ("dosbox") window,
not real-mode DOS.

Rugxulo, I know I need to get an email account and get on "DOS
ain't dead forums"...  But, until then, could you do me another
favor and let Japheth know I posted a patch for HIMEMX to
comp.os.msdos.programmer?  It supports multiple 001 E820h memory
blocks above 1MB.  If you recall, you posted a message or two there
for me previously discussing the issue.

If you do, thanks and sorry for the trouble...
