 This kind of 'always included' header is the '_ansi.h', and the
'sys/config.h' is #include'd from it, and already contains all kind
of machine-dependent things...

 So, here is my temporary patch for the 'sys/config.h' for mingw32 host,
where the SIZE_TYPE and PTRDIFF_TYPE definitions must be removed from the 
CPP_SPEC in specs (until they will pass ok through pexecute and the MS
spawn()) :

--------------- clip --------------------------

 For the MIPS case, there aren't anything like '__H8300H__' for '-mh'
etc., just those '-D__SIZE_TYPE__=...' for '-mlong64' or not, so that
'__LONG_64_BIT__' is my addition for the '-mlong64' case to the specs
(my replacement for the '%{mlong64:-D__SIZE_TYPE=....}' is the 
'%{mlong64:-D__LONG_64_BIT__}'). The '__H8500__' case is unchecked, is
it a '__H8300__' or a '__H8300H__' alike ?

 Cheers, Kai
