Hi,
compiling guile-core-1.8-20061001 under MinGW fails with the following

After removing do_read_without_guile(), read_without_guile,
signal_delivery_thread() and the content of
start_signal_delivery_thread() from scmsigs.c, the build process fails

Does it have pthreads? Did you ask for them, or did configure wrongly
decide to use them?

Yes, but some functions are not supported by pthreads-w32.

No, I didn't ask.

How bad are the missing bits? Should configure reject it because
there's no pthread_sigmask, or is there something the code can do to
cope?

It's not too bad. pthreads-win32 is fairly complete and working.
The mentioned functions are missing because Windows lacks the concept of
signals altogether.

As there are no signals on Win32, I *think* it is okay to just "ifndef
MINGW" the code.
Regarding the undefined "pipe()":
the easiest thing to do would be to define pipe() in the following way:
#include <fcntl.h>
#define pipe(f) _pipe(f, 1000, _O_BINARY)
_pipe() takes two additional parameters: size in bytes and file mode.
Note that these pipes are blocking.

That might be worth trying. (But not with ifdef mingw, rather a test
for missing funcs or features. There's already been mingw-specific
conditionals that became bogus because missing bits have since been
added to the system.)

Yep, we've got that in another file. It might be worth sticking in
_scm.h to get it everywhere.
