This patch also fixes MinGW / MinGW-w64 builds which don't have a prototype declaration for ffsl. Tested-by: Stefan Weil <s...@weilnetz.de> Nevertheless I wonder why you don't use gcc's __builtin_ffsl. Wouldn't it be easier to call ffsl and rely on the compiler to provide inline code? Then adding the missing declaration to include/sysemu/os-win32.h would be sufficient (for MinGW). Stefan
