[TUHS] Building the two-pass Portable C Compiler

[Clem Cole via TUHS]

I believe that is the file you want, since it is defined in the lint
Makefile and given that pcc started out as lint, and given this comment on
the lint READ_ME (note the files are actually: /usr/lib/mip in the 2.11BSD
tree)

/*
 *      @(#)READ_ME     1.2     (Berkeley)      4/8/85
 */
Most of lint's source files are shared with the portable
compiler: they are found in /usr/src/lib/mip.
The files here are only those which are unique to lint.
