The latter was exactly the problem that raised the
question. I corrected it in csa.c, so that the MSVC
compiler woudl accept the code.

One thing I find quirky about this style of programming
(and it is ubiquitous in Java and C++, where declarations
can occur anywhere in the code) is that sometimes, 
changing
the code in a loop forces you to move the declaration
outside the loop, thus increasing the scope of the 
variable.
If that does not happen, however, such a restricted scope
can greatly help understanding the code.

Arjen
