Hi,
I'd stongly vote for checking your changes in --- detailed and informative error messages are more than "handy" for both developers (debugging!) and users --- in case there are any Windows related problems, we should find and solve them, not try to avoid them.
I'm not sure about the error.h (it's never used (directly) in the whole
errno.h it's effect can be mimicked by "extern int errno;", but that is a bit dirty. It is necessary to be able to access the errno variable that at least all io related functions set.
No, you can't use extern int errno; instead of including errno.h. errno could be declared in some weird way, especially in environments that allow multi-threaded programs, so that it *looks* like a simple int but is in fact something else. The C99 standard has this in a footnote: The macro errno need not be the identifier of an object. It might expand to a modifiable lvalue resulting from a function call (for example, *errno()). -- Sjoerd Mullender
