Passing along from inkscape-devel mailing list... The patch closing Bug #63310 (git commit 7cfebce15228c88ee122edb8ba575f9a609e36f4) appears to be broken on platforms that use filename extensions for linked executables. As of cairo-1.14.0, the strings test hardcodes the AC_LINK_IFELSE executable name as "conftest", which is correct for linux and osx, but mingw, it would be "conftest.exe" instead. Using "conftest$ac_exeext" is probably the platform-independent way of getting it correct. For original report, diagnosis, and viability of this solution, see http://sourceforge.net/p/inkscape/mailman/message/32939144/
I also ran into this problem on mingw. I've pushed the patch. http://cgit.freedesktop.org/cairo/commit/?id=f9b65ae1fc91bc558a01c2ad7be5a121c6f10818
