- References: <41637CCD.7040103@renesas.com> <41747A1B.2060609@renesas.com><41748B96.3020106@redhat.com>
This is a patch for glibc to support m32r-linux-gnu target. (Renesas M32R)
Please comit it to mainline.
You haven't listened to what you've been told. The code will not be
added to glibc. You have to maintain the code as an add-on yourself.
This patch is a patch for glibc not using add-on style to support
m32r-linux-gnu target.
Please commit it and regenerate configure.
Regards,
Kazuhiro Inaoka
