+/*
+ This test checks promotion of bitfields.  Bitfields should be promoted
+ very much like chars and shorts:
+
+ Bitfields (signed or unsigned) should be promoted to signed int if their
+ value will fit in a signed int, otherwise to an unsigned int if their
+ value will fit in an unsigned int, otherwise we don't promote them (ANSI/ISO
+ does not specify the behavior of bitfields larger than an unsigned int).
+
+ We test the behavior by subtracting two from the promoted value: this will
+ result in a negitive value for signed types, a positive value for unsigned
+ types.  This test (of course) assumes that the compiler is correctly
+ implementing signed and unsigned arithmetic.
