 Hmm could it be that your default and debian's is like C99?  I suspect
 that maybe mingw64 warns about lower since it has to use Windows C
 runtimes which are questionably at god knows which version of C standard.
 I think the newer are at lest C90 or C99 or so but older like windows xp
 are at C89.  So might be a similar kind of -- this may not work when you
 run it kind of messages like the PRIblahblahblah thing I told strk to
 close.

 I'm not sure if I really need to worry about windows xp or windows 2000
 users since, well technically Microsoft doesn't support them and this is
 just showing a warning in cunit tests and no where else in code.

 Feel free to dismiss this as a won't fix if you want.

 I get similar warning in cu_varint


 {{{
 cu_varint.c:155:2: warning: this decimal constant is unsigned only in ISO
 C90 [enabled by default]
   do_test_s32_varint(-2147483648, 5, "FFFFFFFF0F");
 }}}
