msvcrt is only one of the libcs in MinGW. We therefore replace explictly testing for msvcrt with the isMinGW predicate. This lays the foundation for ucrt64 support.

Some programs, like mailers and web browsers, must be able to convert
|
|
between a given text encoding and the user's encoding. Other programs
|
|
internally store strings in Unicode, to facilitate internal processing,
|
|
and need to convert between internal string representation (Unicode)
|
|
and external string representation (a traditional encoding) when they
|
|
are doing I/O. GNU libiconv is a conversion library for both kinds of
|
|
applications.
