Perhaps - or, at least, require it to support reading gzipped files.

According to some research I did a while ago, the routines used for access to gzipped files:

	inflateInit2() - added in 0.4 (date unknown, but prior to 11 April 1995)
	inflate() - there since Day One?
	inflateEnd() - there since Day One?
	inflatePrime() - added in 1.2.2.4 (11 July 2005)
	inflateSetDictionary() - added in 1.2.2.1 (31 October 2004)
	inflateReset() - there since at least 0.9 (1 May 1995)
