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.
