Bug in System V C compiler

[gwyn at BRL-VLD.ARPA]

For totally mysterious reasons, many UNIX sites will not be running
UNIX System V Release 2 any time soon, and not everyone using C has
a UNIX system anyhow.  Therefore the issue of restricted-length C
symbols remains relevant for a while, until there is an official C
standard requiring otherwise and until a "reasonable" amount of time
for compiler vendors to comply has elapsed.

Note also that the PDP-11 version of UNIX System V Release 2 does
NOT support flexnames.
