SCO 2.1.4[dg] dev sys fault?

[The Super User]

On my SCO Xenix system (2.2.1) with development system (2.1.4 either
d or g, I don't know which) I'm trying to build a package that executes
the command line "cc -Mlt200 -I(some directory) -O -c (somefile).c"
and gets the error
"Make: Cannot alloc mem for envp.. Stop."
*** Error code 1

Stop.


Can someone suggest what is wrong here? I've never seen this before.
Typing the command line by hand compiles without a hitch.

Thanks
