I had posted somewhere the other day about yacc not always being run
after it had been replaced....

Sometimes the problem seems to be that mkdep doesn't get run when
necessary and that means subsequent things don't get done when necessary
either (eg. yacc).

After going through much the same process again on another architecture
I'm beginning to see that lots of the problems are in /usr/src/gnu.  I'm
guessing that the build system over there just isn't as robust.

Actually the current problem I'm noticing is that some binutils things
can depend on header files built in other directories but never
installed in /usr/include where they should be (eg. "bfd.h").  No source
directory should ever look in another's "obj" directory for any
component, and especially not ever a header file!!!!  That's what "make
includes" is for!!!!

This laziness in the binutils area seems to be due in part to the
sillyness using .PATH to pull things out of a "distrib" directory
instead of properly converting the build system and moving everything
into its logical place in the source tree.  What a mess it is now.

Here are some more minor issues that might be encountered by someone
like me who only occasionally makes jumps up to the bleeding edge.  They
are presented in the form of fixes to UPDATING:
