The use of alloca() is quite common for many UNIX applications.
If you intend to port such a program using SAS/C you'd have to
eliminate all alloca()s as SAS/C doesn't supply this function.

There is already another "mostly portable" implementation of
alloca(). However, it does not work with SAS/C as it makes
assumptions about the compiler's handling of the stack-pointer
which are not true for SAS/C.

This is where SASalloca comes in. The idea is to (ab)use the
_PROLOG() and _EPILOG() hooks used by the profiler.

There are no limitations regarding the use of stackextention,
setjmp() and longjmp(), etc. In general, all you have to do is
to compile your sources with PROFILE enabled and to link them
with this alloca implementation.
