I completely agree.

To suggest that path names for source files are not available within
the debugger is clearly nonsense -- if this were the case, it would
be impossible to debug, at source level, unless all source files
were in the current directory.  This surely is not the case; I have
never experienced the slightest problem with gdb, or indeed with
any other debugger.

This would suggest a possible cause for the problem: when building
in place, i.e. with $builddir == $srcdir, then perhaps gcc/g++ *don't*
include the full path name for the source file, in the debug info.  If
this is indeed the case, then again, I agree completely with Werner;
this is simply bad design within GCC.  (Probably I've never noticed
this problem, because I *never* build in place, unless the package
I'm building forces me to do so).
