I'm having trouble finding authoritative information on what VC9 supports (MS don't seem to carry much information on their older compilers - they carry precious little even on the current ones - so I'm depending on Stack Overflow), but it looks like VLAs are *not* supported. Sigh. So I guess I'll change it up. Should I go with alloca, or does Pike have its own preferred way to do this?
I know that alloca does not play well with longjmp. This is not a problem on all compilers, but specifically windows builds can break when using both in the same function. I suppose that C99 arrays are ok once they are correctly supported. I removed alloca from sprintf for instance some years ago because it could crash on windows. Use heap memory if you can.
