What's wrong:
/source/bsd-4.3/vax/lib/cpp/cpp.c, line 130:
# define MAXINC 10
This is the maximum include nesting depth. As a gross generalization,
C++ uses makes more extensive use of #include than C; AT&T Cfront (1.2
and 2.0) uses /lib/cpp (or rather, cc -E) and I've had trouble
building UniDraw (an addition to the InterViews library) because of
this.
What should have happened:
MAXINC should probably be the maximum number of file descriptors. Even
better, it should dynamically reallocate file handles in order to
handle excessively complex code.
Workarounds:
On the RT, I can make Cfront use "hc -nocpp -E" instead, which uses
the built in ANSI preprocessor instead of invoking the (pcc) /lib/cpp.
