2. Added partial debug support for mingw\cygwin targets (the same as
Linux\ELF). Please note, that currently mingw\cygwin uses 'stabs' format
for storing debug info by default, thus many (runtime) libraries has
this information included. These formats shouldn't be mixed in one binary
('stabs' & 'DWARF'), otherwise binutils tools will be confused.
