Re: patch 2.5.4 ISO C90 compliance patch

[Paul Eggert]

Thanks for the patch.  Some comments:

I don't understand the first and third hunks of the proposed change to
patch/patch.c; they seem irrelevant to the issue of porting 'patch'.

I don't understand the second hunk, either.  The emulation package
has fdopen, so why can't it be used here, too?

I assume you fixed the strncasecmp-is-missing bug by using gnulib's
version; that's what I was planning to do.

>From our recent diffutils conversation it appears that changes like
this:

   + #if HAVE_SYS_TYPES_H
     #include <sys/types.h>
   + #endif

won't be needed, as you can arrange for '#include <sys/types.h>' to be
a no-op on your platform by using the appropriate DD statement.
