gdevifno.i

created with:
sh4-unknown-linux-gnu-gcc  -DHAVE_MKSTEMP -DHAVE_HYPOT -DHAVE_FILE64 -DHAVE_MKSTEMP64 -DHAVE_FONTCONFIG -O2 -Wall -Wstrict-prototypes -Wundef -Wmissing-declarations -Wmissing-prototypes -Wwrite-strings -Wno-strict-aliasing -Wdeclaration-after-statement -fno-builtin -fno-common -DHAVE_STDINT_H -DGX_COLOR_INDEX_TYPE="unsigned long long" -O2 -m4 -pipe -DUSE_LIBPAPER -DGS_DEVS_SHARED -DGS_DEVS_SHARED_DIR=\"/usr/lib/ghostscript/8.71\" -I./obj -I./base  -o ./obj/gdevifno.i -E -P ./base/gdevifno.c

and then to hit failure:
sh4-unknown-linux-gnu-gcc -O2 -m4 gdevifno.i -c

[Comment 2 SpanKY 2016-01-12 18:52:20 UTC]

supposed to be fixed in gcc-4.9+
