Since EMX is a port of gcc, you should ask the g++-developpers,
but I think, some points are mentioned in the "reno"-texi-File, which is
included in the EMX distribution (at least it was included in some older
version...); some points that I remember are:
  + gcc (and emx) support 'mutable', which most other compilers don't
  support (yet).
  + gcc supports the new scope rule for for-loops.
  - it does not fully support run-time-type-information, however you might
  try using the -frtti flag (I _think_, rtti is already supported by
  gcc on intel processors, but I don't know how much work is involved
  in porting it to OS/2; just try it, I think you have a fair
  chance...)
  - exception handling was a bit scary for quite some time, but the current
  version doesn't offer an extra flag to enable it any more (at least
  I didn't see it in the documentation), so I guess it should work,
  though I don't use it so far.
  - Template instantiation is rather complicated, but possible. But you
  really need to look at the "Template instantiation"-node of the
  info-File...

  + gcc-2.8.0 is rumoured to fix the mentioned problems
  (will we get emx-0.9d, when gcc-2.8.0 is released, Eberhard?)

Usually,an excellent first reference for questions concerning g++ is
"Mike Stump's Home Page": http://www.cygnus.com/~mrs/
It especially contains a link to "The ANSI C++ Draft and working papers" on
various mirrors and in various formats, e.g.~on
"http://galactose.stanford.edu/~iburrell/cpp/wp-draft/"

Sounds familiar. Heinlein?
