/I have found that a statement such as
/               atof("");
/would help. Anyway, I think that this "feature" of TC is a nuisance.

In TC, the floating point library is only linked in if one of the OBJ files
for the program contained a floating point operation. This is nice because
if you don't use floating point you don't carry around the bulk of the library
code. The downside is this causes a significant burden on the tech support,
as I have seen this one problem appearing over and over again for *years*.

In ZTC, we use the opposite approach. Floating point is always linked in
by default. If you don't need it, then compile with -mi or link in the
INT.OBJ object module. The upside is we never get tech support calls like
the one above. The downside is many people never notice the -mi switch and
wind up thinking that ZTC generates unnaturally large EXE files. Even many
magazine reviewers have fallen into this error.

I'm all ears if anyone has a suggestion on how to get the best of both
by default.
