Do you have a pixman-1.dll? Libtool is very conservative about creating 
DLLs unless all libraries are also DLLs. If one is static or libtool 
thinks one is static then you get the warning and end up with only a 
static lib.
Or am I missing something because it seems that your log shows 
libcairo-2.dll being created. Note that the dll will be in src/.libs
