integer_length: Optimize for MSVC.
* lib/integer_length.c: Include .
(integer_length): With MSVC, use the _BitScanReverse built-in.
With clang-cl I get link-results like:
integer_length_l.obj : error LNK2005: _integer_len
In new code, I'm making intensive use of the functions ffs and ffsll, for
searching in a bitset. So, these functions should better be well optimized,
even for MSVC.
And while at it, also the integer_length* functions.
