Bash on Tru64

make[1]: Entering directory '/usr/users/jay/s/bash-5.1.8/lib/sh'

make[1]: Leaving directory '/usr/users/jay/s/bash-5.1.8/lib/sh'
make: *** [Makefile:692: lib/sh/libsh.a] Error 1

I fixed with:

diff -u input_avail.c.orig input_avail.c

Seems like it might affect other systems?

A few of these:

rm -f man2html.o

I think the flags are ok on the compiler, ignored, but error on the linker.
They should be autoconfed? Eh, they probably are, but then compiler is linker.
Remove them for linking?
I removed a bunch of -W flags unconditionally, and it builds and runs.

Thank you,
