I see from the archives that various people have tried to build
mailutils on Cygwin, most recently here:
http://lists.gnu.org/archive/html/bug-mailutils/2013-12/msg00000.html
I've succeeded in making the build work with the three attached patches.
The main issue is that libtool won't build shared libraries on Cygwin
unless the -no-undefined flag is used. The first patch takes care of that.
But then there are in fact some undefined symbols, which I fixed in the
third patch.
Finally, as was already noted in response to the message cited above,
-llber is needed on Cygwin. More generally, it is needed on any
platform in which the ber_* functions are in -llber rather than -lldap.
I imagine this could be the case on some platforms other than Cygwin, so
I wrote the second patch to apply to any such platform.
Although the three patches are needed for Cygwin, I don't think they do
any harm on other platforms. Please consider installing them.
Thanks.
Ken
P.S. I also have some test failures that I might need help with, but
I'll write about them separately, after I've tried to fix them myself.
