[Mono-devel-list] Mono on AIX [Virus checked]

Winfried,

   Question, why are you setting JIT_SUPPORTED to NO?  Is the AIX ABI 
not SysV compatbile?  mint is all but unsupported and unmaintained 
these days so I'm not that surprised you're having issues with it; the 
way to go (imo)  would be to get the jit working on AIX.

   I'll google around today for the AIX PEM/ABI, I assume a jit port 
wouldn't be difficult.
