enough at detecting compilation errors or at least it has been properly
configured to do so. Configuration heavily depends on this capability, so
if this compiler sanity check fails the configuration process will now fail.

if WINSOCK API is used under WinCE link with 'winsock', else

if WINSOCK API is used link with 'wsock32'.

winsock2.h is available, and library 'winsock' is used when only
winsock.h is available.

when function clock_gettime() is available and the monotonic timer is
also available. Otherwise, in some cases, librt or libposix4 could be used
for linking even when finally not using the clock_gettime() function due
to lack of the monotonic clock.

liberal for me. Also, autoconf 2.61 and earlier doesn't work with icc 10.1
for this macro. (2.62 confirmed to work though). See discusson on the mailing
list starting here:

rely on the ability to compile with or without errors, and is safer than
xlc's default of failing only upon severe errors.
