[Dev-C++] Two questions

Hello,

I am new to this list and to DevC++. I need a c++ compiler and 
IDE that allows one to develop console applications
for Win 32. The applications will serve for numerical computations.
The important requirement is that I need a support
for "long double" variables (that is I need variables more precise than 
"double" variables according to IEEE754). Does DevC++ offer such a 
support? I also need a support for the stl.

A second question is of legal nature. My programming activities
have a scientific character (I work for a university), so that both
the results of my calculations and posssibly also the programs
will be published in the scientific journals, or made publicly available
in source or executable form. Is this allowed by the DevC++ license and
the license of the related compiler(s)?
