You could alternatively edit the config.h file that is generated after
running configure, and change:

#undef HAVE_STRSIGNAL

to:

#define HAVE_STRSIGNAL 1

It seems like the autoconf test did not figure this out correctly.
You can look at the config.log for a report on why it arrived to that
incorrect conclussion.

I think we could do this in a more generic way by putting this on the
acconfig.h file, but for now I have applied the patch directly.

I wonder if mmap() is supported at all by Cygwin.  I am going to try
this next.

The code has special support for dealing with failing mmaps by loading
the file into memory.  Can you single step through raw_buffer_load and
see what it does?
