Subject: Reply to: telecon "c" compiler

I think this problem should addressed:
Many C compilers claim V7 UNIX compatible.  In many cases this is
not as great as it seems, and in some cases an inaccurate statement.
For example,  Whitesmiths C claims v7 compatibility, but there are
subtle differences that make porting very time consuming.  If
I bought a compiler that said V7 UNIX compatible, I would expect
the stdio library (standard i/o) and the printf and the 30 or
40 other things that people expect in a V7 C library to work
without change.  It is not acceptable to edit every printf
in a 3000 line program to make it work right.  I expect to be
able to take a program off a V7 system and have it compile and run
(Of course this excludes UNIX specific things like syscalls),
all the math libraris
all the math libraries should work etc, etc.  I haven't seen a
compiler for a micro that will do this.  I am assuming machine
independent code of course.
