[fpc-devel] line info using dwarf with trunk no longer regognized by gdb

[Martin]

See http://forum.lazarus.freepascal.org/index.php/topic,18816.0.html

I did test myself. Same result on win32. (Run any part of the IDE 
debugger test suite). Tested versions of gdb 6.3 to 7.5

The filename is recognised (when sending >>info line 
"WatchePrg.pas":100<<). Sending a different filename leads to an error. 
But the line number is reported not to exist.
-symbol-list-lines  for the unit returns empty

Exact same commands work with all other fpc versions (including fixes 2.6)
