I hope that this is the right list for compilation issues.

When building libelf-tools.c with gcc 4.5.4 on NetBSD-current/amd64:

In file included from libelf-private.h:25:0,
                 from libelf-tools.c:19:
		 /usr/src/local/xen/xen/include/xen/libelf.h:32:21: fatal error: stdbool.h: No such file or directory

I ran into this problem when trying to apply XSA-55 to xen 4.2.2, but
just reproduced it in -head.

I think this issue stems from a combination of commit 7a549a6aa
...
    libelf: use C99 bool for booleans
...
    In this patch we change all the booleans in libelf to C99 bool,
    from <stdbool.h>.

and

xen/arch/x86/Rules.mk:
ifneq ($(XEN_OS),SunOS)
CFLAGS-$(gcc) += -nostdinc
endif

If I comment out the -nostdinc in Rules.mk, I get a successful "make xen".

(One mystery: why aren't you all seeing this?)

Cheers,

Patrick
