1540-0063 (S) The text "eventqueue_t" is unexpected.

[F2guy]

I am having a problem compiling my code. The following error is displayed:
make
mpixlcxx -c -O3 potentialqueue_local.cpp
mpixlcxx -c -O3 eventqueue.cpp
"eventqueue_remote.h", line 20.36: 1540-0063 (S) The text "eventqueue_t" is unexpected.
make: *** [eventqueue.o] Error 1

I am fairly new to C++ and not sure if the problem is in the makefile or maybe one of my #include statements. Can anyone see the problem?

It seems that the problem was

#include "neuron.h"

from eventqueue.h, but I do not see why it gave that error.
