That's because a.out files do NOT include information about where the
segments should be located!  go32 will ALWAYS place .text at 0x1020
and .data at the first available multiple of 0x00400000.  Go32 does
still support COFF files (I think - not tested recently) which *DO*
have this information, so if you need go32 to do this you will need to
convince ld to produce COFF output.

However, if you do relocate the text higher there is NO way to get
anything useful in the 0-0x3ffff range at all, as go32 will not put
anything there.  If you have a special requirement, you will need to
either modify go32 or use something else.
