Patch for Cygwin environment

[Makino Takaki]

Dear commonc++ developers,

I'd like to post a patch to make commonc++2 compilable in a latest
Cygwin environment on Windows.  It seems that the commonc++2 package
cannot be compiled via configure script on current Cygwin release.
I hope that the patch helps development of this excellent library.

The following patch is to fix the compilation error for pthread
emulation of Cygwin. It would be more efficient if I could make use of
native Win32 API, but it seems a lot of patching effort...
I confirmed the patch on Cygwin 1.3.19 and commoncpp2 1.0.8.  

The changes are:
 * Remove !defined(__CYGWIN32__) from #if surronding PosixThread class.
 * Disabled PosixThread::waitSignal when sigwait() is not available. I'm
   not sure why sigwait() is disabled on Cygwin, and I don't know
   what workaround is available for it.  Anyway it seems working happily
   without PosixThread::waitSignal member function.
 * Added some stuff for socklen_t.  Current configure script cannot find
   socklen_t in Cygwin; socklen_t is #define'd under cygwin/socket.h,
   but configure applies EGREP_HEADER to only sys/socket.h.  Though my
   patch for this problem may be too naive...

Best regards,
