Compiling With Borland C++ Builder And DEBUG

I've found a few things during compilation of cgicc from today's CVS that
look like they could use some fixing.

1.  In CgiUtils.h, LOGLN is #defined to dump s and STDNS endl, but I think
STDNS has gone away to be replaced by std::.

2.  On lines 159 and 174 of CgiEnvironment.cpp, as well as a number of
places in FormEntry.cpp, atol() and atof() are used without std::.

3.  The return statement in CgiInput::getenv() has a string and a char * on
either side of the colon, which Borland complains about ("two operands must
evaluate to the same type") but I think that's a Borland bug since I believe
the standard allows different when one can convert to the other.  I just put
the second operand in a string constructor ("string(var)") to make it
explicit.

Pretty minor stuff!
