[Tinycc-devel] alloca for tcc - first cut

[David A. Wheeler]

I've attached a first cut implementation of alloca for tcc.  This one allocates 
cleanly straight off the stack - no monkeying with malloc() at all.  It 
currently doesn't actually call the bounds-checking functions, though I know in 
principle what it needs to call.  Runs on Linux; _may_ work on Windows, but I 
suspect that there's some oddities involving page access that would need to be 
accounted for.

My thanks to those who have sent me constructive criticism!
