Perhaps you could try with gcc to check if it is the compiler choice 
that is triggering errors. See below

VM_LABEL macro definition in picked up from the file:
----- platforms/unix/vm/sqPlatformSpecific.h
108 #if defined(__GNUC__)
109 # if !defined(VM_LABEL)
110 #       define VM_LABEL(foo) asm("\n.globl L" #foo "\nL" #foo ":")
111 # endif

How did the __GNUC__ get defined in your compilation?

You could try passing -D'VM_LABEL(foo)=0' while compiling to work around 
this problem temporarily.
