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 âlibxl_domain_suspendâ:
libxl.c:262: warning: ignoring return value of âwriteâ, declared with attribute 
warn_unused_result
In function âopenâ,
    inlined from âlibxl_create_device_modelâ at libxl.c:512:
/usr/include/bits/fcntl2.h:51: error: call to â__open_missing_modeâ declared 
with attribute error: open with O_CREAT in second argument needs 3 arguments
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);
