Subject: (VAX & RT) Version 6.4R: cpp "Unreasonable include nesting"


System type, version:	(RT/PC, CVAXSTAR) Version 6.4R
System name:		portnoy, e40-008-7
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.

Beginning at line 25 of /usr/andrew/lib/tpls/letter.tpl see the following:

\define{display
menu:[Region~4,Display~14]
attr:[Flags KeepPriorNL Int Set]
attr:[Flags KeepNextNL Int Set]
attr:[LeftMargin LeftMargin Inch 32768]
attr:[RightMargin RightMargin Inch 32768]}
attr:[Justification LeftJustified Point 0]}
\define{example
menu:[Region~4,Example~12]

Note the extra closed curly brace at the beginning of line 30. This
leads to any "letter" having attr:[Justification LeftJustified Point 0]}
at the beginning. [This is on the RT with the Andrew locker attached.]
