Hi All,

A few days a go, I posted a request for information on making a library being 
constructed in VC++1.00, available to DJGPP.  After a bit of thinking, I 
realised it might be better, and advantageous, to continue this project in 
DJGPP itself.  But, I have a few questions:

1.  Apart from a few syntax changes (Ie, taking the '_' from in front of some
    library functions), is there anything I else I should be aware of?  Is 
    there any C++ facilities that are not support by DJGPP.  I don't think I
    have done anything extra-ordinary.  Most of the work is classes, and 
    derived classes.  If anybody has had any experience with VC++1.00, and
    they know of any problems I might have, please, could they tell me? :)

2.  I saw a posting today, about the results of 'Malloc'.  I am under the
    impression that DJGPP's malloc can reserve memory greater than 640k?  Is
    this true?  If so, what sort of pointers do I then need to use?  Can I
    just use it like standard Malloc, only for larger amounts of memory?

3.  Due to the sheer amount of class objects I use, and the inheritance, and
    virtual functions, this GUI is quite memory intensive.  As DJGPP can use
    lots of memory, does it store classes in this area aswell?

I do hope there will not be any problems during this conversion.  It would be
nice to make this GUI available to DJGPP, with an application builder and IDE.

Any help would be appreciated :)
