RE: Unable to build Bison with PGI compilers

[Stewart, Adam James]

Paul,

You're absolutely right, I guess I'm the only one out there using the PGI 
compilers haha. I added your patch to our package manager:

https://github.com/LLNL/spack/pull/3044

Dozens of tests fail during `make check`, but I'm less concerned about that.

This is the same as the problem you reported against GNU M4 last March.
PGI by default does not support the C99 'inline' keyword properly. A
workaround was installed into Gnulib here:

http://git.savannah.gnu.org/cgit/gnulib.git/commit/?id=6c58857620e62135b0b748df436008eb3c3a23d6

This fix should appear in the next Bison version, whenever it comes out.
In the meantime you can apply the Gnulib patch to your copy of Bison,
and run 'make'; you'll need developer tools like Autoconf installed to
do that.

I expect PGI's lack of support is inadvertent: that is, I suspect the
PGI folks think that PGI supports C99 'extern inline', but the support
is buggy. As a PGI user you might file a bug report with them, and you
can point them at the Bison 3.0.4 source code as an example of the bug.
