From 9c61296405d4299b7000e445a6e07c0232bb0342 Mon Sep 17 00:00:00 2001 From: Tom Tromey Date: Tue, 7 Aug 2018 12:07:36 -0600 Subject: [PATCH] Allow CPPFLAGS to be set on the make command line While looking into PR build/8751 (which seems to be fixed), I noticed that it's not possible to change CPPFLAGS for gdb on the "make" command line. It's reasonable to want to do this sometimes, and I think this patch should suffice. gdb/ChangeLog 2018-08-07 Tom Tromey * Makefile.in (CPPFLAGS): New variable.
