I have added mumps through the third party directory and now the configure script
completes.

There is a warning and the config output says to report this to coin-or. This is what
was output.

configure: WARNING: winsock.h: present but cannot be compiled
configure: WARNING: winsock.h:     check for missing prerequisite headers?
configure: WARNING: winsock.h: see the Autoconf documentation
configure: WARNING: winsock.h:     section "Present But Cannot Be Compiled"
configure: WARNING: winsock.h: proceeding with the preprocessor's result
configure: WARNING: winsock.h: in the future, the compiler will take precedence
configure: WARNING:     ## --------------------------------------- ##
configure: WARNING:     ## Report this to coin-os at list.coin-or.org ##
configure: WARNING:     ## --------------------------------------- ##
checking for winsock.h... yes

let me know if you would like me to post the entire config output.
