I'm afraid it takes more than changing

  #ifdef linux

in the Imake.cf to

  #ifdef __linux

I just tried it with XFree86, which won't build with pgcc v1.1.  (By
"won't build" I mean that the symbol LinuxMachineDefines is not
evaluated.)  The #ifdef change resulted in XFree not being able to find
some of its header files.

Sigh.  I sure would like to build XFree with pgcc.
