[Mono-list] specifying autoconf 2.13?

[s_e_gallo]

Hi,   My installation of cygwin contains both the stable  autoconf-stable-2.13-4.tar.bz2 and the development version autoconf-devel-2.52-4.tar.bz2, and I'm having trouble building mono c-sharp on my system. How do I force the use of the stable version in the c-sharp build process? Thank you.   Sincerely,   Steve Gallo
