Martin Storsjö	b4d9fa6cb9	compat: Fix the fallback definition of stdc_trailing_zeros While shifting "value" to left, we would iterate through all bits of an unsigned long long, while we only expect to count through "size * CHAR_BIT" bits; instead shift bits to the right and just count the trailing zeros. This fixes fate with MSVC. Signed-off-by: Martin Storsjö <martin@martin.st>	6 months ago
