The trigraph warnings are currently disabled in mainline, and trigraphs themselves are disabled in GCC unless explicitly enabled. My series contained a patch that changes all trigraphs by adding '\' characters, to let us no longer disable the warning and slightly simplify the command line: drivers/atm/idt77252.c | 2 +- drivers/gpu/drm/msm/msm_rd.c | 2 +- drivers/mtd/maps/sun_uflash.c | 2 +- drivers/net/ethernet/marvell/mvneta.c | 2 +- drivers/net/wireless/broadcom/brcm80211/brcmfmac/sdio.c | 2 +- drivers/s390/block/dasd_proc.c | 2 +- drivers/scsi/imm.c | 4 ++-- drivers/scsi/ppa.c | 4 ++-- drivers/tty/serial/sunsu.c | 2 +- net/rose/af_rose.c | 4 ++-- sound/isa/msnd/msnd.c | 2 +- Sorry you ran into this after you picked up the patches to the Makefile but not my preparation patch. I was unsure about whether this is worth changing, so I did not send that one patch from my series and we can probably just not drop the -Wno-trigraphs flag. Arnd
