Just would like to ask the Xen-Devel team what version of GCC compiler 
they are using to Compile the Xen 4.2-Unstable from the xen-untable.hg 
repository?

Just curious since i always have such a hard time in compiling the 
latest Xen 4.2-Unstable as it always aborts with errors.

The last changeset of Xen 4.2 i was able to compile was 
"*25392:3d98fb95e735*" and ONLY after removing patch 25364 (*hg backout 
-r 25364*), otherwise it wouldn't compile either.

That trick doesn't seem to work with any changesets after that and even 
revision "*25432:d7318231cfe3*" ends with an error:

libxl.c: In function 'libxl_primary_console_exec':
libxl.c:1233:9: error: case value '4294967295' not in enumerated type 
'libxl_domain_type' [-Werror=switch]

SO, possibly the GCC compiler is at fault and was wondering what version 
the Xen-devel team uses?

Thank you very much
