While that is true, the BITEST/BIT_SIZE couple is special in that the
first differing character is a letter in one and an underscore in the
other entry.  This means that exactly *those* entries will sort
differently when sorted "upper cased" vs. sorted "lower case".

I should have been more careful with strcasecmp (the man page explicitly
states that the case-insensitive compare will be effected by converting
both names to lower case - which is just the wrong way for solving this
problem).

I'm now testing a patch that uses a specially written "compare upper
case", that will convert the would-be-intrinsic-name to upper case when
comparing it with the first of the three entries from the table. 
AFAICS, this should correct the problem.
