Just a guess (post your source next time)
but I'd say you have inline assembly in your program.  
DJGPP uses AT&T syntax, which is quite different.  See the FAQ for 
details on how to convert.

Off the top of my head - 

Post a b,w,or l after each instruction mnemonic to indicate the size
and do not use word ptr type size overrides.

registers must be preceded with a %.
Immediates must be preceded with a $
Source and destination are reversed.
Memory addressing is (I think)
displacement(base,index,scale)
Note that you use parenthesis and commas to separate

so 

inc word ptr [esi]

becomes

incw (%esi)
