When cfront runs over ~raeburn/compiler-bugs/cfront/align.c, the code
it generates is incorrect. In the routine
AlignCmd::GetReference(GraphicComp*)
or
GetReference__8AlignCmdFP11GraphicComp
the call to the Iterator constructor returns a pointer to an Iterator,
which is then passed to Clipboard::GetComp. However, that routine
wants an Iterator as an argument, not an Iterator*. The C++ code is
correct in that respect; the code generated by cfront is not.
This happens with both the vax and RT versions. Because I set the
default for cfront on the RT to ANSI mode, this gets caught by hc; the
non-ANSI code on the vax will not cause a compiler warning, but it
will not function properly.
I've compressed the files in that directory to save a little space.
Please let me know when they can be deleted.

P.S. Ezra -- when you file a report with AT&T, be sure to ask for a
patch for cfront 2.0. Their fixing it in future versions won't help
us until we get a new license.
