+Subject: [PATCH] diffstat: fix wrong evaluation of CC
+
+Upstream-Status: Inappropriate [oe specific]
+
+m4 function CF_CC_ENV_FLAGS checks whether variable CC contains options '-I', '-U'
+and '-D'. It is not suitable for oe that option such as '-D_FORTIFY_SOURCE=2' may
+be included in CC. And then CC will be wrongly filtered.
+
+So comment out CF_CC_ENV_FLAGS from function CF_PROG_CC.
