And later, this:

gcc  -O1 -fno-omit-frame-pointer -fno-optimize-sibling-calls -m64 -g -fno-strict-aliasing -std=gnu99 -Wall -Wstrict-prototypes -Wno-unused-value -Wdeclaration-after-statement  -D__XEN_TOOLS__ -MMD -MF .libxl.o.d  -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE  -I. -fPIC -I../../tools/libxc -I../../tools/include -I../../tools/libxc -I../../tools/include -I../../tools/xenstore -I../../tools/include -c -o libxl.o libxl.c
libxl.c: In function ‘libxl_domain_suspend’:

    inlined from ‘libxl_create_device_model’ at libxl.c:512:

make[4]: *** [libxl.o] Error 1
make[4]: Leaving directory `/nfs/anthrax/brendan/remus/xen-unstable.64/tools/libxl'

Looks like the mode argument is missing here:

    logfile_w = open(logfile, O_WRONLY|O_CREAT);
