#import vs #include

[Artem Baguinski]

quoting http://gnustep.made-it.com/GSPT/xml/Tutorial_en.html :

  In Cocoa, #import is used instead of #include to prevent duplicated
  declarations. But GNU GCC doesn't support #import as good as Apple's
  GCC, and GNUstep use #include.

is that statment correct? what's wrong with GNU GCC's #import support?
and BTW doesn't G in GCC stand for GNU?
