pjrc-8051 README
^^^^^^^^^^^^^^^^

This port uses the PJRC 87C52 development system and the SDCC toolchain.

The PJRC 87C52 development system can be obtained from http://www.pjrc.com/.

The SDCC toolchain is available from http://sdcc.sourceforge.net/.  All
testing has been performed using verison 2.6.0 of the SDDC toolchain.

Building the SDCC toolchain
^^^^^^^^^^^^^^^^^^^^^^^^^^^

The SDCC toolchain is built with the standard configure/make/make install
sequence.  However, some special actions are required to generate libraries
compatible with this build.  First start with the usual steps

  download
  unpack
  cd sdcc
  ./configure
  make

But before installing,

  Apply sdcc-2.6.0.patch
  cd sdcc/device/lib
  make model-mcs51-stack-auto

Then

  cd sdcc
  make install
