Replace seven nominally MD implementations of frexp() that are broken

for subnormals with one implementation that works.

Implement the classification macros isfinite(), isinf(), isnan(), and

2004-07-09T03:32:40+00:00

isnormal() the hard way, rather than relying on fpclassify().  This is
a lose in the sense that we need a total of 12 functions, but it is
necessary for binary compatibility because we have never bumped libm's
major version number.  In particular, isinf(), isnan(), and isnanf()
were BSD libc functions before they were C99 macros, so we can't
reimplement them in terms of fpclassify() without adding a dependency
on libc.so.5.  I have tried to arrange things so that programs that
could be compiled in FreeBSD 4.X will generate the same external
references when compiled in 5.X.  At the same time, the new macros
should remain C99-compliant.

The isinf() and isnan() functions remain in libc for historical
reasons; however, I have moved the functions that implement the macros
isfinite() and isnormal() to libm where they belong.  Moreover,
half a dozen MD versions of isinf() and isnan() have been replaced
with MI versions that work equally well.

Define LDBL_MANH_SIZE and LDBL_MANL_SIZE to be the sizes of the

Provide sysarch(2) prototypes in the MD sysarch.h headers. While I'm

thus matching the documentation.

Remove the now extraneous (and now conflicting) function declarations
in various libc sources.  Remove now unnecessary casts.
