Subject: Compile memmem.o without -Werror.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=eff1410f2bf0e295ffd7cbd2848af76fedfa0c62;p=binutils-gdb.git

Compile memmem.o without -Werror.

This reproduces the same approach as in GDB to allow us to build
specific files without -Werror.

gdb/gdbserver/ChangeLog:

        * Makefile.in (INTERNAL_CFLAGS_BASE): New variable. Extracted
        from INTERNAL_CFLAGS.
        (INTERNAL_WARN_CFLAGS): New variable.
        (INTERNAL_CFLAGS): Adjust, using INTERNAL_WARN_CFLAGS.
