Subject: [PATCH] Undefine "extended" macro temporarily on GNU Hurd

GNU Mach microkernel header files (gnumach-dev 1.8+git20201129) added to
struct i386_xfp_save in /usr/include/i386-gnu/include/mach/i386/fp_reg.h
a new "extended" field which happens to collide with the macro definition
"#define extended double" in FontForge, leading to FTBFS on GNU Hurd.

This issue may be circumvented by temporarily undefining the "extended"
macro before loading `<gio/gio.h>` and friends, and redefining the
"extended" macro right after.
