            Bug ID: 97183
           Summary: zstd build failure for gcc 10 on Ubuntu 16.04
           Product: gcc
           Version: 10.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: bootstrap
          Assignee: unassigned at gcc dot gnu.org
          Reporter: wilson at gcc dot gnu.org
  Target Milestone: ---

This was originally reported here
    https://github.com/riscv/riscv-gnu-toolchain/issues/718

A build of gcc 10 on Ubuntu 16.04 with the libzstd-dev package installed gives
multiple errors.  Ubuntu 16.04 has zstd version 0.5.1 which lacks features that
gcc is trying to use.  The gcc configure test for zstd.h only verifies that it
exists, it doesn't verify the version, or that any of the functions or macros
we need are present.

Ubuntu 18.04 has zstd version 1.3.3, I verified that builds.  So we can maybe
verify the version is 1.3.3 or greater, or maybe check for the specific
functions and macros that we are trying to use.

Kito did a little research that suggests that we need verfsion 1.3.0 or
greater.  We haven't tried to verify that.

--without-zstd successfully works around the problem.
