help with Solaris gcc2.8.1 compiler

[Laudel, Ken]

Anyone,

I inherited a C++ program which was written in the mid ninetees and
developed on the PC in Visual C++. I am supposed to make modifications
and get it compiled and running on a Solaris workstation. The compiler I am
using is Solaris gcc2.8.1 (help shows "GNU tools -  last changes 1993"). 
Everything compiles correctly and runs. The only problem I have is when the
program tries to create a data file with a filename >32 characters. It will
create
the file without truncating any characters, but no data gets written into
the file.
If I make the filename one character less, everything works fine. It does
not
seem to be a problem inherent in the code, since I can run the code on the 
PC and it works with the longer filenames.
In addition, other applications I use on the workstation, such as MATLAB, 
have no problem creating data files with filenames comprised of >32
characters.
I am guessing there is some sort of compiler switch I can use to enable 
longer filenames (?). Any insight/help/things to try would be greatly
appreciated.

Thank You,
Ken
