Fixes #28102

(In reply to comment #1)

Because the rules in config.gcc say so:

*-*-gnu*)
...
    i[34567]86-*-*)
      tm_file="${cpu_type}/${cpu_type}.h i386/unix.h i386/att.h dbxelf.h
elfos.\
h svr4.h linux.h i386/linux.h gnu.h ${tm_file}"
...


Here is a patch that fixes the problem.

       * config/i386/gnu.h (TARGET_C99_FUNCTIONS): Undefine macro.
