argv weirdness with latest snapshot

[BHOLAM at uk dot ibm dot com]

You wanted some testing of the latest snapshot for the upcoming 1.1.5 so
here goes.

I have a program that uses the Windows API CreateProcess to run another
program. This is a very small program which I compile using -mno-cygwin.
If the execed program is a non-cygwin program then the argument list is as
expected.
If the execed program is a cygwin program then the argument list also
includes the parent program.
I only see this behaviour with the latest snapshot, 1.1.4 was OK.

Attached should be a small testcase exec.tar. Just extract and 'sh runme'.
The child program just prints the number of arguments and the argument
list. With 1.1.4 you should see:

$ sh runme
Run no-cygwin child
1
C:\home\mike\db2\ntclp\winchild.exe
Run cygwin child
1
/home/mike/db2/ntclp/cygchild.exe

With the latest snapshot you see ( notice the difference in the argument
list when running the cygwin child):

$ sh runme
Run no-cygwin child
1
C:\home\mike\db2\ntclp\winchild.exe
Run cygwin child
2
./exec1
cygchild.exe

I am willing to entertain the possibility that I may not be using
CreateProcess correctly as my Windows programming is not that strong but
there is certainly a
difference in behaviour between 1.1.4 and the latest snapshot.

(See attached file: exec.tar)
