I have no opinion on specifics, but it's one possible choice.
Note that the use of malloc() is still there -- I think there 
are two orthogonal issues (for something as simple as wrapping 
alloca()!)

1) how to wrap it:
a use a C++ wrapper allocator
b use FREEA()

2) how to allocate:
c use malloc()
d use a linear allocator
e combination

I think that if I did it, I'd end up with a/e, but any of the 
combinations will work.

The ## token concatenation has been well supported in ANSI C 
for at least the last 10 years. I use it daily on GCC3 and 
MSVC6.

Cheers,
