     ./configure seemed to complete fine, but I'm missing a bunch of file lock
     constants.  Here's the make output:

     c_incl/cache.c:297: for each function it appears in.)

     make: *** [c_incl/cache.o] Error 1
     
     
     Any advice would be appreciated.  Has anyone got the distributed compiling
     working in Cygwin?
     

Cook under Cygwin works fine for me.

It looks like you need to first install the relevant library which
provides posix locking.  I can't tell you which one it would be.


But you said that configure `completes fine'.  But did you have a look
at the logs it produces?  It probably says something like `Looking for
flock: no'.  Maybe configure.ac should be changed to give an error if
it can't find the appropriate libraries.
