Posix-spawn won't compile under Cygwin w/ Ruby 1.9.3-p0

[muraii]

I hope this is the appropriate spot for this. I know Windows support is low on the pole, and it's understandable. If there is some part of the M I need to RTF, please let me know.

Below is the result of my invoking "gem install jekyll" with Ruby 1.9.2 installed in Cygwin on WinXP. I ran into this same issue when using the Cygwin-default Ruby 1.8.x, but even upon uninstalling this and compiling Ruby 1.9.3-p0 I get the same error. I mention this because in my research I came across some discussion pointing to a difference in how 1.8 and 1.9 handled posix-spawn.

This is the content of gem-make.out. Thank you for any help you can provide.

I've just opened a pull request (see issue #20) to deal with that.

[rtomayko]

Merged #20. Thanks for the report and the patch.
