* Move macro QEMU_GNUC_PREREQ to compiler.hStefan Weil2011-09-231-1/+1
| | | | | | | | | | | | | The macro is compiler specific and does not depend on the operating system. Move macro QEMU_GNUC_PREREQ from osdep.h to compiler.h and use it to simplify existing code. host-utils.h uses this macro, so it now needs compiler.h instead of osdep.h.

* Include <strings.h> for ffs().balrog2008-11-121-24/+24
| | | | | | | | | | | | ffs() is in <strings.h> although bsd compatible systems have it in <string.h> already. ffs() is used in omap1.c, omap2.c, omap_i2c.c, bt-sdp.c. These uses can be replaced with clz32() but ffs is more available. Problem was spotted by malc. Make host-utils.h formatting more consistent. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@5708 c046a42c-6fe2-441c-8c8c-71466251a162
