It seems strncasecmp is POSIX 2001 (according to opengroup.org) in
<strings.h>, not in <string.h>

Not sure about this, related to sigaction, and it seems to be an XSI
extension, defined in POSIX 2001. I don't know why gcc fails.

POSIX 2001:
The <sys/select.h> header shall define the fd_set type as a structure.

It is under _XOPEN_SOURCE in <sys/select.h> here (debian unstable gcc
4.3) though.
