How to make M-X compile import my environment?

[Roy Smith]

I'm using XEmacs 20.4 on a Solaris box in a ClearCase build
environment.  Our "make" command is a shell alias to "clearmake -C
gnu", and that in turn relies on lots of environment variables to work
right (I have no control over this stuff).

The problem is, when I run M-X compile, the shell that's spawned to
run make doesn't inherit my environment.  It doesn't seem to read my
.cshrc file either.

Any ideas what might be going on?
