ad403413c7 a ton of gzip changes, split up in compiled and 
run-tested pieces. Code was rather messy.
It's not a bug fix, more like code cleanup.

This is the first part.

67b23e6043 getopt_ulflags -> getopt32. 
It is impossible to formulate sane ABI based on
size of ulong because it can be 32-bit or 64-bit.
Basically it means that you cannot portably use
more that 32 option chars in one call anyway...
Make it explicit.

64d7e93081 - convert a few xopen3(,,0) into xopen(,). Also peruse the fact that xopen defaults to 0777 on it's own, so we don't need to xopen3(,,0777). 
Saves a few bytes:
