Hi,

I have recently downloaded Borland's C++ command line compiler,
version 5.5.1. It's been some time since I've used any of the Borland
compilers, but I have a fair amount of experience with 3.0, 3.1, and
4.0. As a user of vi, I have always preferred to maintain my projects
with make and command line compilers.

During the development of a small project I started recently, I
encountered an error that I could not make heads or tails of. In the
attempt to try troubleshooting the problem, I decided to copy the
relevant source code to another file. In this case, I copied the
source file PollUtil.cpp to test.cpp, without making any modifications
to the source code. I copied and pasted the relevant lines from my
makefile, and changed references from ‘PollUtil' to ‘Test'. There are
no conditional compilation statements in my source that are based on
the source file name.

What's driving me nuts is when I try to build the two applications,
which are built using the same compiler and linker options, and the
same libraries, I obtain two executables with different sizes. This is
somewhat understandable due to issues such as debug symbols.

What isn't understandable is why the two applications execute
differently. I am obviously targeting Win32, and there are no static
resources to load. The app is a GUI app, although it does fire up a
console window. Does anyone have any ideas where I can look to find
out why these two executables run differently?

Thanks in advance,

David
