[SciPy-dev] more 64 Bit testing (was linspace)

Hi,

now I managed to have another closer look at the compile problem
with dfitpackmodule.c.

Some facts ahead
- this is with intel icc
- dfitpackmodule.c is generated via f2py
  (it is explicitely written at the start of that file -
   sorry for not making this clear in the very begining -
   I jumped straight to the error ...)
- The error is
  build/src/Lib/interpolate/dfitpackmodule.c(2528): error: expected a ";"
         int calc_lwrk1(void) {
- the code looks alright to me
  (but after too long exposure to python I would not
   be able to spot a missing ";" anyway )
- the same file compiles fine with gcc!

So does this mean the code uses something which is specific to gcc?
Maybe some (ic)C expert can spot the problem??
(Somehow I am tempted to say that this is a bug in icc ...)

Any ideas are appreciated. I attach the corresponding section of
the code below (line 2528 is marked by <=====).

Best, Arnd
