1) must install gcc as described in INSTALL
2) run make from this directory
3) after building gcc, rename tstcpp in the @sys directory

 cd @sys
 ln -s tstcpp cpp

4) Set prefix for gcc to locate cpp, cc1, etc

 setenv GCC_EXEC_PREFIX /afs/cs/project/midway/src/compiler/gcc-1.37/@sys/

5) must unsetenv to return to regular compiler.

 unsetenv GCC_EXEC_PREFIX
