My *guess* would be that the turbo-c compiler is much more ANSI compliant
than the older compilers used on your BSD/Ultrix systems.  If you really
need to be portable accross these environments I would develop the software
on the BSD/Ultrix system and then port it to turbo-c. This gets you writing
the software at the "least common denominator" level of compiler.  An ANSI
compiler should not have too much trouble compiling software generated
under an older (K&R 1st Ed) compiler since that was part of thier mandate.
