Talking about PROGMEM, pgmspace.h etc.

I was having some difficulty addressing arrays of strings in flash-ROM while
using variable indexes on an ATmega8. Found out the problem was already
reported as #13427 in bug reports. I tried having a look att the bug report
but didn't get any wiser as to the current status of this error. So I was
wondering:
a) Is this bug dealt with,
b) What needs to be done, compiled, downloaded to deal with it and
c) Is there some simple solution to this problem that I have missed through
sheer lack of skill?

Otherwise pgmspace seems to be what I need.
