I tried to build cmake 2.2.2.
./configure dies looking for sys/wait.h, which MinGW and MSYS don't have.
d:/devel/mingw/cmake-2.2.2/Source/kwsys/ProcessUNIX.c:54:37: sys/wait.h: 
No such file or directory
and then a pile of errors

I edited ./bootstrap so that KWSYS_C_SOURCES=ProcessWin32 and got much 
farther compiling *.o files, but upon linkage I got a lot of undefined 
symbols.  It looks like this script assumes Unix and has no 
configuration for Win32.
