I usually compile files in DOS prompt.
Just type "gcc xxx.cc" or "gxx xxx.c".
Read documents in gcc/rhide packages.

Objective-C is another program language similar to C, and OO similar to
Smalltalk. Default extension of Objective-C programmes in gcc is ".m".

Program mixed Objective-C and C++ is called Objective-C++. DJGPP cannot
compile it well.

C++ is nearly a superset of C. Or you can .o files which compiled from C
and C++.

Many compilers have their own "add-on" function. You cannot compile
programmes which use those functions. But most of them (include gcc) can
compile ANSI-C programmes.

No, you can't.
Copying header files to DJGPP directory only is usually useless, unless you
can find their library in .a format.

Oh! What is this ?

char p[]="char p[]=%s%s%s,e[]=%s%s%s%s,q[]=%s%s%s%s;main(){printf(p,q,p,q,q,
e,e,q,q,e,q,q);}",e[]="\\",q[]="\"";main(){printf(p,q,p,q,q,e,e,q,q,e,q,q);}
