When using the following ./configure the configure system appears to not
correctly detect the presence of sys/sysmacros.h which generates errors
involving undefined major and minor-nomarkup objects.
./configure --with-platform=pc \
--prefix=/usr \
--sbindir=/usr/bin \
--enable-nls \
--enable-device-mapper \
--enable-boot-time \
--enable-cache-stats \
--enable-grub-mkfont \
--enable-grub-mount \
--disable-werror

make[2]: *** [Makefile;6227:

To work around this issue I'm explicitly setting
ac_cv_header_sys_sysmacros_h=yes
Additionally during the configure I get the following warning:
configure: WARNING: sys/sysmacros.h: present but cannot be compiled
configure: WARNING: sys/sysmacros.h: check for missing prerequisite
headers?
configure: WARNING: sys/sysmacros.h: see the Autoconf documentation
configure: WARNING: sys/sysmacros.h: section "Present But Cannot Be
Compiled"
configure: WARNING: sys/sysmacros.h: proceeding with the compiler's result
