* Description:
** Prototypes of system calls
** One should in principle use stdlib, however on the various machines,
stdlibs do not always agree, I found easier to look by hand
and copy here my human interpretation of what I need.
Examples of problems are: reservations for multi processor
architectures on some Silicon machines, necessity to define myFile_t on
some machines and not on others etc.

MALLOC_ALIGNMENT
Alignment of most restrictive data type, the system malloc will
return addresses aligned to this, and we do the same in messalloc.
STACK_ALIGNMENT
Alignment of data objects on a Stack; this should really be
the same as MALLOC_ALIGNMENT, but for most 32 bit pointer machines
we align stacks to 4 bytes to save memory.
STACK_DOUBLE_ALIGNMENT
Alignment of doubles required on stack, if this is greater than
STACK_ALIGNMENT, we read and write doubles on a stack by steam.
Put specific exceptions first, the defaults below should cope
with most cases. Oh, one more thing, STACK_ALIGNMENT and
STACK_DOUBLE ALIGNMENT are used on pre-processor constant
expressions so no sizeofs, sorry.
