Re: Bison 1.875 won't build on Tru64 4.0 Unix

[Tony Leneis]

        Well, I installed GNU M4 (which needs some updating for modern
compilers - it didn't think Tru64 had tmpfile() or vprintf() because the
test programs run by configure prototyped them wrong.)  Anyway, I still
can't build bison 1.875 easily because configure doesn't build a makefile
in the main directory.  I can manually cd to lib and src and run make in
there, but when I run the tests something (I presume bison) is dumping
core on one of the tests.  I decided to give up on it for now, since 1.35
seems to work OK and 1.875 is clearly in need of some additional work.

        Back to the M4 thing, I have nothing against M4, it's just a
hassle to have to install another version in /usr/local as a prerequisite
to build bison when there's a workable version of M4 provided by the vendor.
