No, system() under djgpp is supposed to inherit the entire environment
of the parent process.  I suppose it's possible that his SHELL variable
doesn't specify enough memory for the environment, and some of the
variables that are added by the djgpp startup code are getting chopped
off in the call to system().

To the original poster:  Try editing your 'config.sys'.  Find the line
that says "SHELL=C:\DOS\COMMAND.COM" or something similar.  It might say
"COMSPEC" instead of "SHELL".  Add " /E:2048" to the end of that line,
save, and reboot your computer.  This can't hurt anything and may help
solve the problem.
