I've got some files that are compressed using GZip's specification.
However, they don't have the headers I presume GZip has such as checksum,
filename, something like that in the beginning. It starts off right into
the compression with the 3-bit intro thing that each section does to tell
which type of compression method in GZip it is using and whether it is the
last one, etc.

How can I use ZLib to decompress this?

zlib has a "raw" inflate mode for decompressing RFC 1951 deflate
streams. Please read the documentation in zlib.h.
