1c6d2ff03d
This patch just fixes a limited number of bits not conforming to c99 by using
- __asm__ instead of just asm
- {0} instead of {} for struct initialization
- h_addr_list[0] instead of h_addr to access the host address in
struct hostent
- #include <strings.h> where needed (for ffs and strcasecmp)
Based on a previous patch by Carl-Daniel.
Corresponding to flashrom svn r1585.
