Thanks for the suggestion. I tried it and it didn't work. I've edited
src/Makefile.in to add:
echo_cflags:
echo "$(ALL_CFLAGS)"
Here are the flags that I obtained and passed to `c-macro-expand':
-Demacs -I. -I. -I../lib -I../lib -pthread -I/usr/include/gtk-3.0
-I/usr/include/atk-1.0 -I/usr/inclu
de/at-spi2-atk/2.0 -I/usr/include/pango-1.0 -I/usr/include/gio-unix-2.0/
-I/usr/include/cairo -I/usr/inc
lude/gdk-pixbuf-2.0 -I/usr/include/glib-2.0
-I/usr/lib/x86_64-linux-gnu/glib-2.0/include -I/usr/include/
harfbuzz -I/usr/include/freetype2 -I/usr/include/pixman-1

-I/usr/include/freetype2 -I/usr/include
/freetype2 -I/usr/include/freetype2
Is there a working / better way to get these flags. I wouldn't want to
reconfigure just to get the flags.
