commit dc18f036f161e1e49e1d001046716c77d1699e70
Author: Richard Levitte <levitte at openssl.org>

    Fix util/mkpod2html.pl to call pod2html with absolute paths
    
    It turns out that on VMS, pod2html only recognises VMS directory
    specifications if they contain a device name, which is accomplished by
    making them absolute.  Otherwise, a VMS build that includes building
    the document HTML files ends up with an error like this:
    
        $ perl [---.downloads.openssl-3_0-snap-20210916.util]mkpod2html.pl -i [---.downloads.openssl-3_0-snap-20210916.doc.man1]CA.pl.pod -o [.DOC.HTML.MAN1]CA.PL.HTML -t "CA.pl" -r "[---.downloads.openssl-3_0-snap-20210916.doc]"
        [---.downloads.openssl-3_0-snap-20210916.util]mkpod2html.pl: error changing to directory -/-/-/downloads/openssl-3_0-snap-20210916/doc/: no such file or directory
        %SYSTEM-F-ABORT, abort
