Update maintainer mode to support debug wait points.

Make a spin() method available when compiled in maintainer mode.
If a file exists in the working directory with a specific name,
make will sleep until the file is deleted.

Ensure that maintainer mode is enabled on Windows, using the same
algorithm we use on POSIX / autoconf systems.

* build_w32.bat: If maintMakefile exists, enable maintainer mode.
* src/main.c (main): Replace Windows-only suspend flag with spin().
* src/makeint.h: A SPIN() macro calls spin() in maintainer mode.
* src/misc.c (spin): If a spin file exists sleep until it's deleted.
