egcs installation problems

[J Douglas Winters <winters at cs dot utah dot edu>]

I ran into two problems when installing egcs on my machine.

1)	On my Linux distribution (and I imagine others, as well) there are
	links in /usr from cc -> gcc and from c++ -> g++.

	If you install into, for example, /usr/local this can cause a
	problem.  Specifically, the egcs install does not create its own
	links from cc and c++ in the install directory.  This might
	normally go unnoticed, it just means you use an older compiler
	once in a while.  It becomes more serious if changing something
	the old compiler depends on.  (I.e., I upgraded to glibc2.  Then,
	tried reinstalling egcs, and it couldn't detect my macine type
	because configure.guess was executing cc (my old libc5 gcc) and
	the resulting program was segfaulting. )

2)	Some of the permissions are not properly set.  I don't recall all
	of them, but the libgcc.a, libiberty.a and libstdc++.a are a few.
	Also, if I remember correctly, if it created /usr/local/include,
	those permissions weren't set properly either, though I'm not
	certain of this.

Thanks.
