[RFA] Avoid Cannot read 0x20000000 on cygwin GDB

[Pierre Muller <muller@ics.u-strasbg.fr>]

This has been discuss long ago, 
and I thought it was in CVS already for a long time,
but apparently noone committed it.

Back in september 200, I probably didn't dare to commit it myself,
but my commit list grew quite a lot since that time!

See http://sources.redhat.com/ml/gdb-patches/2000-09/msg00107.html

If I get an second approval from 
any of the Blanket Write Privs (as blockframe.c 
does not seem to belong to some designated group),
I will commit this ASAP.

ChangeLog entry:

2000-09-12  Pierre Muller  <muller@ics.u-strasbg.fr>
	* blockframe.c (get_pc_function_start): return 0 if the minimal symbol
	found is not inside a section.
