This is for memcached 1.4.4

This occurs in Cygwin as well.  It occurs with at least 1.4.4 1.4.3.

can you configure with CFLAGS=-save-temps then attach util.i ?  I think this is 
related to the isspace() macro.

I have the same problem. util.i attached is from a Solaris9/sparc system.

Confirmed fixed here. memcached 1.4.4 now compiles on Sol9/sparc with no errors 
with
this change to util.c.
