Why? After all, this is what you want. BTW, they are not really declared as
being re-entrant, you just tell the compiler that you will take care that
the routine will not be called from an interrupt thread while it's being
run from the main thread.

I'm not sure what you mean by "standard". A C compiler that uses a static
stack and creates non-reentrant code is in that respect non-standard, so if
you want that, you need to use a different compiler. However, such code on
a PIC 18 is in general less efficient.

OTOH, with PICC-18, declaring such a function in the appropriate way (that
is, telling the compiler it is ok that it appears in both the main call
tree and an interrupt call tree because you are taking care that it won't
be in the routine in both threads at the same time) /is/ the standard way
of treating this kind of situation.
