Description

Create 100 char (0..90..9...) folder and subfolder with same name in current working directory.
Put copy of "trnsport.gdx" from "gams trnsport gdx=default" with 104 char name (0..90..9....gdx) in innermost folder (and second copy with ...2.gdx name)
Determine absolute path of GDX files

Then make sure:
- gdxdump can dump the GDX
- gdxdiff can diff the GDX with its copy
- gdxmerge can merge the GDX with its copy

Actual test is a Python script, as CMEX cannot handle long texts well yet.
