Restore __eprintf

[Jeffrey Oldham]

My recent upgrade to the latest dejagnu for mips-sgi-irix6.5 revealed
hundreds of libstdc++-v3 test failures all because `__eprintf' is
declared but not defined.  __eprintf() is declared in a
mips-sgi-irix6.5/include/assert.h.  assert.h is included by
libstdc++-v3/include/c_std/bits/std_cassert.h.  See the attached file
for an example.

gcc/Makefile.in includes `__eprintf' in LIB2FUNCS_ST.  These functions
are included only in the static library version.  Unfortunately, the
`-static' flag is, in practice, ignored for Irix.  The only solution I
see is to remove all uses of `__eprintf' in all the gcc source code
and then comment LIB2FUNCS_ST as being dangerous since `-static' does
not work on some machines.

Questions:
1) Is omitting `__eprintf' from LIB2FUNCS_ST acceptable?
2) How is assert.h created?

In the mean time, I will test omitting `__eprintf' from LIB2FUNCS_ST
on mips-sgi-irix6.5 to see if this resolves the problem.

Thanks for your help,
Jeffrey D. Oldham
