Re: Advice for Interix and to specify users

[Mark D. Baushke]

Hi Jerker,

The following patch to rcs.c may aid you in finding out more information
about your fopen() bug. I would commit it to the CVS sources, but I have
a pending change ([bug #22781]) which is still waiting for one of the
other cvs developers to successfully build on a Windows box in my tree,
so I have not tested this patch.

        Good luck,

        * rcs.c (rcsbuf_cache_open): Pass errno to error() calls from
        CVS_FOPEN and fseek on failure.
