well, it's a little bit different.. how's it resolved concerning license if
DJGPP sutff (esp. DPMI) is utilized to develop/distribute commercial dos
application? According to legal restriction term on DJGPP application, it
says ok just to include the infomation in product's documents on how to get
DJGPP.

Are there any other agreements except this? and would you let us know any
commercial dos s/w built over DJGPP?
