DJGPP has less problems than MinGW because DJGPP is more Posix
compliant.  E.g., out of the non-msdos constructs you mentioned, DJGPP
has `signal', `select', and inodes.

But yes, quite a few of Unixish assumptions already bit the dust since
the DJGPP port is part of GDB.  IS_ABSOLUTE_PATH and similar
abstractions come to mind, as does DIRNAME_SEPARATOR.  Undoubtedly,
this is one reason why the MinGW port additions were relatively minor.
