You might find comfort in the fact that the next release of DJGPP will
stop second-guessing your $SHELL.  The new version of `system' should
allow you to use a Unix-style shell at its full power (it looks at the
value of $SHELL in the environment and uses that).  The 4DOS .btm
extension is also supported, as well as direct execution of shell scripts
with no extension.  The new version of Make will also use $SHELL in the
same circumstances where Make on Unix would call a shell.  If you would
like to help testing the next version, please contact me for details.
