The joy of compiling

Allright /g/, I'm trying to build a program from source in Windows with MinGW and it seems it needs Berkley DB libraries. After running [sh ../dist/configure --enable-mingw --enable-cxx, I try to make it but it gives me an error that I don't know how to solve. It gives me this output:
../dist/../dbinc/repmgr.h:502:13: error: two or more kind of data in the specificators of the declaration
../dist/../dbinc/repmgr.h:502:1: notification: name of type without use in an empty declaration [activated by default]
Does someone how can I fix that? When opening repmgr.h, line 502 says typedef int socklen_t;, but I'm afraid of modifying it and breaking something. What can I do?

Allright /g/

Yes, I made a bad copypaste from my thread on /g/ because there they seem to be unable to help me. I'm sorry, I will take more care next time.

Perhaps socklen_t is already typedeffed in another header?
