I believe overlap of functions in the same expression was disallowed by
the response to defect report 087. The only reference I've been able to
find right now (since the committee seems to have removed the C89 DRs from
their site) is in the response to DR 287 which includes:

"Proposed Committee Response
As noted in the response to DR 087, function calls in the same expression
do not overlap. This has not changed for C99."
