How do I compile the C perfect minimal hashing library on windows?

I've installed mingw and Msys.

I've run bash configure to create the make file.

But when I run make I get the following output

E:\cmph-1.1>make
make  all-recursive
make[1]: Entering directory `/e/cmph-1.1'
Making all in src

I'm struggling to work out what I need to do to make it compile.

Look at this patch that contains the fix to compile on mingw : http://sourceforge.net/p/cmph/patches/3/

If you look in that that header file, you'll see near the top this construct:

#ifdef WIN32
// include headers to use gettimeofday
#else
    #ifdef __GNUC__
    #include <sys/time.h>
    #include <sys/resource.h>
    #endif
#endif

It looks like you're not ending up in that second half, from where you'd get the declarations of gettimeofday() and struct timeval.

I'm not very familiar with MinGW - does it define WIN32? If so, you might need to rework that preprocessor logic to do what you want. For reference, it works fine in cygwin.
