The Tandem port was done on a Cyclone machine running D20.
The port is pretty clean and all facilities seem to work except for 
some of the I/O piping stuff which is just too foreign a concept for
Tandem.

Usage is as for UNIX except that D20 requires all "{" and "}" characters
to be escaped with "~" on the command line (not in script files) and the
standard Tandem syntax for "/in filename,out filename/" must be used
instead of the usual UNIX "<" and ">" for file redirection. (Redirection
options on getline, print etc are supported.)

The -mr=val option has been "stolen" to enable Tandem users to
process fixed-length records with no "end-of-line" character. That
is, -mr=74 tells gawk to read the input file as fixed 74-byte
records.

To build a Tandem executable from source, down-load all of the files
so that the file names on the Tandem box are, for example ARRAYC or
AWKH. That is, make all of the file names conform to the restrictions
of D20. The "totally Tandem-specific" files are in the tandem
"subvolume" and should be copied to the main src directory before
building gawk.

The file compit can then be used to compile and bind an executable.
Sorry, no make and no autoconfig.

This is my first UNIX port to Tandem so I may well have missed the best
way of doing things: I just desperately needed a working awk at a 
Tandem shop.
