If I type gcc at the c:, I get back
 c:/djgpp/bin/gcc.exe version 1.10oe2 Copyright (C) 1991 DJ Delorie
Usage c:/djgpp/bin/gcc [program [options . . . ]]

if I type gcc -c hello.adb I get the message
Can't open file <-c>

If I type gcc hello.adb -c I get the unknown file type message. I get
the same error if I leave out the -c.

I did not have gcc installed before I installed GNAT. If I do a search in
all directories for gcc.* I only find gcc.exe in c:\djgpp\bin.

Several people have emailed me suggesting other things; I get the 
impression that all had gcc installed before GNAT. I used the 'minimal
gcc installation' provided with the GNAT distribution. My suspicions are
that if I install a full gcc, then install gnat, things will work.

I guess I better email gnat-report as someone suggested.
