Flang arg_parser fails to accept input on stdin

Flang does not accept input on stdin. It generates an error.
For e.g : flang -o - -S -x f95 - < ex.f90
F90-F-0000-Internal compiler error. Unknown command line argument: 0

function f(a)
  real a
  f = a*a
  return
end

While the eqiuvalent clang command works fine and generates assembly.
For e.g : clang -o - -S -x c - < ex.c

float f(float a)
{
  return a*a;
}

Ignore this for now: It is a Work in Progress

Do not fork or build from this repository. After discussions with the Flang community, we thought we would try to create a fork of the LLVM Clang repository to house the changes necessary for Flang, analogous to what we are doing with the mirrored llvm repository.

Creating the fork named flang-driver is the first step in that process.

Build failure on latest checkout of release_60 branch (32f15e1)

Hi --

The latest checkout of the release_60 branch fails on OpenBSD/amd64. This is what I use for the official OpenBSD package of flang, since it matches the version of LLVM we use. Yes, I use the OpenBSD-provided LLVM instead of your LLVM, because it would significantly raise the maintenance burden for flang to use yours (just a function of having to maintain yet another package, not a commentary on your decision to use your own LLVM).

Relevant part of the build log below. Let me know what I can do to help.

Thanks!
