gnupic: Thread: gpsim-0.17.4

Here's a patch to fix a serious bug (that's been in gpsim since day 1 but
caught by Ralf just now):

or you can get the whole tar ball:

The bug (actually two bugs) occurred if you attempted to access indf while
fsr was equal to an alias indf (e.g. if fsr == 0x80 on the 14bit core,
then an access to indf would dump core). There was no problem if the fsr
pointed directly at indf (e.g. if fsr == 0).

The other bug (gui compiled code only) was if fsr pointed to an invalid
register (e.g. 0x7f on the pic16f84) then gpsim would dump core if you
accessed the indf.

The 18cxxx stuff is not affected by either one of these bugs (I hope).
