The shell-command procedure under the MinGW build of Gambit 4.6.2
seems to be broken.
When running gsi under the MinGW MSys shell (by running gsi.exe -:d-),
things worked
fine under Gambit 4.6.0 (as shown below). However, in Gambit 4.6.2,
it appears that
only the program name passed in the shell command is being recognized.
Thus, I could
run (shell-command "ls 1 2 3") while in a directory where no such
files existed, and I
got the contents of the directory (as if the command had only been
"ls", with no arguments).

==== Output running under Msys: (gsi.exe -:d-) ==========

The results get even worse when running Gambit 4.6.2 directly from the Windows
start menu. Here again, version 4.6.0 does what I expected. However,
when I run
version 4.6.2, I can't get the shell-command to work no matter what
command I pass it:

--------------------------------------------------------------

All of these tests were run against the current prebuilt versions of
Gambit 4.6.0 and 4.6.2 downloaded from Gambit's web site.

I'll be happy to test any patches or other changes needed to fix this problem.
