Ah!  The occurrence of this error means that you successfully installed
gpc-971001 including the new RTS.  :-)-:

As far as I can look up from the Linux on-line C documentation, `qd'
is a standard format.  Some C compilers comply to this standard, while
others use `lld' or `Ld' for putting out `long long int'.  GCC should
support all of these variants, so I wonder what is going wrong on EMX.

The same problem holds, BTW, for the DEC Alpha. :-(

If anybody knows a portable way to output `long long in' in C, please
let us know, so we can improve GPC's RTS.  (I know, I am asking this
question to the wrong mailing list ...)
