This compiler is better in at least three ways than the 1.1 compiler:
   1.  It produces better object code (fewer bytes and faster execution)
   2.  Compilation speed is improved
   3.  A number of bugs have been fixed

It is my experience that on the whole, the object code size is smaller
than the PC-IX compiler without the -O flag, and about 6% larger than
the PC-IX compiler with the -O flag.  I have not tested it on other
compilers.  That is left as an exercise for the reader.  The difference
between MINIX and PC-IX varies considerably from program to program.
If anyone publishes measurements later, be sure to run tests on a large
sample to get meaningful measurements.

As with the Pascal compiler described in a companion posting, this
compiler belongs to the Vrije Universiteit, which uses the royalties
on sales to fund graduate student travel.  Please do not further
distribute the compiler.

The various passes of the 1.2 compiler are not plug compatible with the
1.1 compiler.  You have to use all of 1.1 or all of 1.2.  Mix and match
won't work.

While on the subject of compilers, I should perhaps mention that we have
a running Modula 2 compiler, and are working on porting it to MINIX.
The VAX and SUN-3 versions are currently undergoing heavy testing.
The Modula 2 compiler follows the same structure as C and Pascal, only
with mem instead of cem or pem as the front end, and an additional
library for the Modula specific routines.
