Absolute filenames (or at least more than just the name) are a must for 
some cases.

iF you debug a library, then you start some launcher app, which loads 
the library. Both launcher app, and library may contain a unit called 
"Foo". Yet the 2 Foo may be different units from different locations.
With just the filename, the debugger can not handle this.

As for debugging the exe on a diff computer. The IDE will try by 
filename only, if full path can not be found.
This fallback is also needed, because older gdb have some problems 
finding a unit by full path, if .. are in the name (which is the case 
for at least the lazarus.exe).
