Martijn Dekker 3de4da5afb Remove Microsoft/Cygwin import/export nonsense
Windows/Cygwin requires onerous special handling and the definition
of additional _imp__* symbols to import/export symbols between
dynamically linked binaries. Its support in AST used a lot of
macros and code obfuscation. In the features/common test for this,
AT&T called this the "Microsoft import/export nonsense".

They're right, it's nonsense. Somehow, Microsoft's POSIX layer,
SFU/Interix, always managed without it. No one has time to maintain
this (especially considering how incredibly sluggish Cygwin is).
And in fact, it had already fallen victim to bit rot; I confirmed
this in my early experiments with reintroducing dynamic library
support. No one has time to fix it, either.

So, my apologies to any Cygwin fans; ksh 93u+m will never support
dynamically loadable built-ins on Cygwin, even when I do manage to
reintroduce dynamic linking properly.
