Wouldn't it be simpler, and easier to understand, to just use the version
numbers CYGWIN_VERSION_DLL_MAJOR, CYGWIN_VERSION_DLL_MINOR from
<cygwin/version.h>?

It's in autoconf's spirit to not test version numbers if you can test the
feature itself (in this case: some feature of stdio). But testing another
unrelated feature?
