* final.c (label_to_max_skip):
Due to the change given below. Ada compiler under all platforms is no longer
able to build libraries. The path to TOOLS_TARGET_PAIRS is incorrect in
gnattools/Makefile.in resulting in the use of the dummy mlib-tgt-specific.adb
for all platforms.

Now, these very long strings are caught at compile-time when possible. We
should also add runtime checks, for non-constant lengths; three such examples
are given in comment #9.

Basically, I created a class with two constructors. One of those is
trying to call the other one. The call doesn't seem to have any effect
