It does not have DPMI support built-in. CSDPMI however works.

Tried in Fedora-19 x86_64 under DOSBOX 0.74. All least 'gcc -v' works.
The available memory amount may be a problem for compiling larger sources
though

Also: one can use DOSEMU under Linux.
- DPMI is supported.
- I have not suceeded to got more than almost 1Gb or DPMI memory (Dosemu begins to crash)
- LFN is supported. However LFN support was not really compatible with DJGPP libc last time
   i checked. One may need to rebuild many tools using current CVS version of DJGPP
