Hallo J.J.

JJvdH> >I must include djgpp.lnk manually, though.
JJvdH> When I said 'specs' I meant 'djgpp.env'
JJvdH> The 'specs' and 'specs.gpc' file should not be touched!
I copied the [gcc] section of *djgpp.env* to [gpc].
And the linker ld cannot find something with ..._ctor_... and _dtor_.
until i include djgpp.lnk manually into linking.

JJvdH> This was a remark by Peter, but he was probably confusing unix and=
 dos.
JJvdH> Not sure you can redirect stderr in DOS.
Yes, i read something it's impossible in DOS.
:-(

JJvdH> I only heard rumours, but if you watch the djgpp newsgroup

u may

JJvdH> ftp.delorie.com
I'll try it.

I noticed that the GNU-integer is *not* the same as the BP-integer.
:-)

It seems that the =ABret=BB-instruction at the end of the program causes =
the
exception. if you use a halt() as the last command in the source-file,
it will work correctly. A bug in the compiler ?

JJvdH> The 'asmname' could have been just a 'C' directive, but then you w=

Why not?
If it is possible to disable those ugly underscore-warnings... ?!

JJvdH> crazy memory issues in DOS. I'm not sure you need all this DPMI st=

No, i'll try to write my own system-unit and I'll try to access
the LFB of an VESA card.
