-  I've tracked down a weird bug in Perl5.6.1 to the UTS compiler's
-  mishandling of MY_UV_MAX in util.c.  It is defined as
-    #ifndef MY_UV_MAX
-    #  define MY_UV_MAX ((UV)IV_MAX * (UV)2 + (UV)1)
-    #endif
-  The compiler handles {double floating point value} >= MY_UV_MAX as if
-  MY_UV_MAX were the signed integer -1.  In fact it will do the same
-  thing with (UV)(0xffffffff), in place of MY_UV_MAX, though 0xffffffff
-  *without* the typecast to UV works fine.
