When looking at errno.h in 1.12m4 I noticed that a lot of DOS return 
codes are not mentioned there.

Q1: Although not defined, will /all/ dos error codes still be returned ?

Also I noticed a difference between the definitions in my DOS reference 
and the definitions in errno.h:

Error    DOS Meaning                                     DJGPP Meaning
-----    ----------------------------------------------  --------------
0x13     Attempt to write on a write-protected diskette  Invalid argument
0x15     Drive not ready                                 Exec format error
0x20     Sharing violation                               EPIPE
0x21     Lock violation                                  Math argument
0x22     Invalid disk change                             Result too large

Q2: Are those errors returns indeed replaced by DJGPP ? If so, where have 
    the orignal errors gone ? Or is my DOS reference wrong ?

Finally: Yes, I know V2 is out there now, but since every attempt to 
compile GNAT (GNU Ada) for V2 has as yet failed I am still stuck at 
using V1 for the moment.
