C compiler for learning C

[rupp at cod.UUCP]

This is probably a frequently posted question, so forgive the repetiton.  Can
someone recommend a good C compiler running under ms-dos which is appropriate
for a computer-literate user who wants to learn C?  Ideally, it should
be a package including an interpreter as well as a compiler, with
complete and clear error messages.

Regarding interpreters, is there an interpreter for C that would be a good
enhancement to a C compiler?

Cost is a factor, but the learning considerations are more important.

Thanks much.
