Is this really right?
+be32dec(const void *pp)

+ unsigned char const *p = (unsigned char const *)pp;
The "const *" is harmless enough, but dropping the
leading "const" doesn't seem right at all: 'pp'
is a pointer to const data, 'p' points to
modifiable data.
Um, both point to const data. `unsigned char * const p' would point to
non-const data, and casting to that should cause a diagnostic.
This is just a style bug -- the const qualifier is placed in the usual
but confusing place for pp and in the unusual but easier to understand
place for p.
Other bugs in the above include namespace pollution (at least for the
original copy in <sys/endian.h>) -- both p and pp are in the application
namespace. This bug is missing in older MD endian.h code.
