Earie et Al,
You seem to have hit the nail on the head. CMD.exe is a standard NT app
(of course) and my CmdLineLook app is also compiled with MSVC (produces
standard NT executables). However, if I use John's source code and
compile within Cygwin, I get the following results from the same
makefile, but with the two command line inspectors as the shells...
CmdLineLook -i "BEGIN { $^W=1; }"
0 -F:/GAP/NEWDEV/GAP/TESTING/TEST1/LATEST/ANOTHER/CmdLineLook.exe-
1 -/c-
2 -CmdLineLook -i "BEGIN-
3 -{-
4 -$^W=1;-
5 -}"-
CmdLineLook -i "BEGIN { $^W=1; }"
arg 0: <//F/GAP/NEWDEV/GAP/TESTING/TEST1/LATEST/ANOTHER/prtcmd.exe>
arg 1: </c>
arg 2: <CmdLineLook -i "BEGIN { $^W=1; }">
What does this tell us? It seems to suggest that standard NT C runtime
code is different between Cygwin and MSVC. This is good to be finally
getting to the bottom of the problem.
I guess what I really need to do is rebuild CMD.EXE with the Cygwin
toolkit!!! Wonder whether I can get the source code.
If I cannot rebuild CMD.EXE, is there anything I can do in the make
syntax to get it to put things in the way I need them to be for standard
NT executables? Any guesses? As mentioned before, when there are no
quotes on the command line, GNUmake outputs stuff differently from when
there is, as demonstrated below. However, when running the
Cygwin-compiled shell, it appears the same. It must, however, be doing
something different, mustn't it, or is the change in fact in the C
runtime itself. Now I am confused.
Can anyone help out here?
CmdLineLook -i BEGIN { $^W=1; }
0 -F:/GAP/NEWDEV/GAP/TESTING/TEST1/LATEST/ANOTHER/CmdLineLook.exe-
1 -/c-
2 -CmdLineLook -i BEGIN { $^W=1; }-
SHELL=F:/GAP/NEWDEV/GAP/TESTING/TEST1/LATEST/ANOTHER/CmdLineLook.exe
F:\GAP\NEWDEV\GAP\TESTING\TEST1\LATEST\ANOTHER>make
CmdLineLook -i "BEGIN { $^W=1; }"
0 -F:/GAP/NEWDEV/GAP/TESTING/TEST1/LATEST/ANOTHER/CmdLineLook.exe-
1 -/c-
2 -CmdLineLook -i "BEGIN-
3 -{-
4 -$^W=1;-
5 -}"-
SHELL=F:/GAP/NEWDEV/GAP/TESTING/TEST1/LATEST/ANOTHER/CmdLineLook.exe
Thanks everyone for their help so far.

Hmm. I bet you used cygwin to build your program didn't you.
Whereas
Kevin
used MSVC to build his. If you build your program with mingw32,
you'll
have
the same problem as Kevin.
