[Dev-C++] A few more questions

[Leslaw B. <nbb...@cy...>]

Hi,

I am beginning to work with DevC++ and MInGW compiler, and I have a few
questions:

1) I notice that the method name() of the type_info object returned by 
the operator typeid() does not return the exact class name (when called
for a class object), but the class name preceded by some digits. Is this
a normal behaviour or some bug in the compiler?

2) I have experimented a bit with the long double variable type,
and I notice that it does, in fact, have an improved precision
over the standard double variables. However, it is not possible
to substitute a long double variable with a value exceeding the
range of double variables (values greater than about 1.0e308).
I have experienced a similar problem with the Borland C++ Builder.
Is there any way to force the long double variables to accept
the values from the entire range theoretically expected for these 
variables?

3) I notice that the size of the executables (for console type 
applications) exceeds several times the size that I have previously
obtained by using Borland C++ Builder. Is there any way (compiler 
options?) to reduce this size, and what is generally the reason
for this behaviour?

4) After compiling successfully a pretty largish project,
I get quite many warnings:

[Warning] unknown escape sequence '\T'

These seem to occur either in files indicated in the compiler
message window (bottom of the IDE screen), or the name of the file
is not indicated. An attempt to click on the message, to see
the place where the warning occurs, does not work. What can be
the reson for these messages, and how to eliminate the problem?

5) I wonder if anybody has experiences with creating DLLs that
cooperate with MS C++ Visual Studio - produced GUIs?
This is something that I need to do, because I need long double
variables offered by MInGW and DevCPP, but Visual Studio should
be better for making a GUI, although it does not provide
support for long doubles. Will such a combination work?
