+by S. C. Johnson, written in the late 70's. 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 is to look for pcc, gcc, clang (in that order).
+
+This build is for the 1.1.0.BETA branch of pcc. The 1.0 branch 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).
+
+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.
+
+Note: 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.

+
+# 20141031 bkw:
+# - took over maintentance.
+# - upgraded for 1.1.0 beta series.
+# - combined pcc and pcc-libs into one build, since either one is
+#   useless without the other.
+# - removed pcc-lib's 002-build-libpcc-with-pcc.patch as it's been
+#   applied upstream in the 1.1.0 branch.
+# - use private /usr/libexec/pcc/ dir instead of installing stuff
+#   directly in /usr/libexec. Probably just paranoia.
+# - rename cpp-pcc man page to pcpp, since the beta installs a
+#   /usr/bin/pcpp.
+# - get rid of -j1 in make command, seems to no longer be needed.
+# - add logic to choose which compiler to use if CC not set.
+# - extract license from source, install to /usr/doc
+
+# notes:
+
+# - pcc 1.0 hasn't worked since Slackware 13.37. It builds & installs
+#   fine, but anything compiled with it just segfaults in the
+#   startup code. Hence the upgrade to a beta snapshot, which at
+#   least can compile a working "hello world" on Slack 14.1.
+
+# - upstream only keeps about a weeks' worth of snapshot tarballs, so
+#   so I'm self-hosting them. I do plan to update the snapshot version
+#   from time to time, but *not* on a weekly basis. Eventually 1.1.0
+#   will be released, and there will be much rejoicing.
+
+# - upstream filenames are pcc-1.1.0.BETA-<yyyymmdd>. If you want to
+#   try a different snapshot, set VERSION=1.1.0_beta_<yyyymmdd> in
+#   the env. AFAIK, the pcc and pcc-libs snapshot dates must always
+#   match (this script enforces it).
