Re: [9front] Nim lang, C alignment support

[Adrian Siekierka <asiekierka@gmail.com>]

Hello,

The Nim garbage collector? I hope you're opting into ARC/ORC instead - 
that's the one the Nim development team is pushing for (the former is 
reference counting with RAII elements; the latter is that combined with 
a dedicated garbage collector just for resolving references which may 
contain cycles).

I think Araq might be interested in patches which improve the 
portability of the C code they output, but you'd have to ask.
