We have released Texinfo 6.1, the GNU documentation format.

I had the compilation warnings shown at the end of this message when
building this with MinGW on MS-Windows.

I ignored the realloc warnings: they seem to be due to fighting
between Gnulib redefinitions and Perl headers redefinitions, and I see
no way of avoiding them.  They also seem harmless.

Seems harmless to me as well.

The popen/pclose issue seems more serious; I fixed it like this:

I see this code is in the #ifdef _WIN32 section, so I'm happy with it
even if I don't understand it.

One worry I have is why Perl is redefining popen/pclose in the first
place and if problems could occur on other systems, like Cygwin. (Ken

No, I don't get any such warnings on Cygwin.
