While playing around with Wget 1.14 (specifically, with its new,
Gzip-compressed WARC (Web ARChive) files), I discovered a VMS-specific
Gzip problem.
Previously, on VMS, Gzip was rigged not to work properly on
multi-member gzip archives (such as the ones created by the new Wget).
For some while, my Gzip-for-VMS kits have used a stream-access mode
(open() with "ctx=stm") on compressed files, but the C macro RECORD_IO
was still defined (in tailor.h), and this caused Gzip on VMS to exit
after processing the first member of a multi-member Gzip archive, which
could be disappointing, if one expected complete output.
New source and complete kits which should solve this problem are
available at the usual place:

A "gdiff -u" for "tailor.h" (original 1.5 v. my latest):
