yes, RHIDE is somewhat similar to borlands (dos based) IDE,  it can handle
many different languages if you have the compilers installed for them...
(with GCC installed it's do C, etc)

the official web page is/was
http://www.tu-chemnitz.de/~rho/rhide.html

There may be a mandrake RPM for it there or elsewhere if not theres source...

it works here. EG,

#include 
 main(){
   puts("You "
 #ifdef FOO
        "defined"
 #else
        "didn't define"
 #endif
        " FOO");
   return 0;
 }


OTOH AIUI
 #if defined( SYMBOL )

is the same as
 #ifdef SYMBOL

there's a manpage. and also the "libc" manpages for each function...

 man gcc
 man 2 intro
 man 3 intro

if you installed info you can also do

 info libc / info gcc

which will get you similar info in a different format, and RHIDE has a
built-in info reader too.

on the other hand I'm fairly sure there's an IDE that runs in emacs,
I know there's an info reader in emacs...

 NH> A preferred web site?

there may be a gcc web page at the FSF website  (fsf.org or gnu.org?)
