+pcc (Portable C Compiler)
+
+pcc is based on the original Portable C Compiler by S. C. Johnson,
+written in the late 1970s. About 50% of the frontend code and 80% of
+the backend code has been rewritten.
 
 Build options (environment variables):
+
 TLS - Enable thread local storage? Default=no, export TLS=yes to enable.
-CC - Compiler to use. Default: look for pcc, gcc, clang (in that order).
+CC - Compiler to use. Default: look for pcc and clang (in that order).
+     It's no longer possible to use CC=gcc.
+
+Notes:
+
+1. To bootstrap pcc, first remove any old versions of pcc
+   (and pcc-libs, if present), then build and install pcc twice
+   (without setting CC). The first time, pcc will be built with
+   clang. The second time, it will be built with itself.
 
-This build is for the 1.1.0 release of pcc. The 1.0 release no longer
-works on modern Slackware versions (newer than 13.37). The old pcc
-1.0 had separate builds for pcc and pcc-libs; this build includes the
-libraries so no separate pcc-libs is needed (or exists).
+2. This build is for a post-1.1.0 snapshot of pcc. The 1.0 release no
+   longer works on modern Slackware versions (newer than 13.37), and
+   the 1.1.0 release no longer works on Slackware 15.0. The old pcc
+   1.0 had separate builds for pcc and pcc-libs; this build includes
+   the libraries so no separate pcc-libs is needed (or exists).
 
-Optional step: To bootstrap pcc, first remove any old versions of pcc
-(and pcc-libs, if present), then build and install pcc twice (without
-setting CC). The first time, pcc will be built with gcc. The second
-time, it will be built with itself.
+3. pcc is a C compiler only. There is experimental, incomplete
+   support for C++ and Fortran 77 in the pcc codebase, but neither is
+   usable yet.
