You would rather throw away djgpp entirely, and get the DOS extender RSX
together with EMX. Provided you use only functions that are common to DOS
and OS/2 (read the EMX libref doc), EMX executables are interchangeable 
between OS/2 and DOS. THere is almost nothing you can do with djgpp which
has no counterpart in EMX (the converse is not true).

From the a.out format, both should be at least similar (although a.out is not
a.out) but there may be subtle differences you won't encounter immediately,
but for linking you would at least need both sets of runtime and C libraries,
so you might end up with two compilers then.

Except graphics stuff.  
(emx/gcc and djgpp are much different here.)
