Ramsay JonesAlthough sysinfo() is a 'Linux only' function, cygwin provides an implementation which appears to be functional. The assumption that this function is Linux only is reflected in the way the HAVE_SYSINFO build variable is handled by the Makefile and config.mak.uname.
Rework the setting of HAVE_SYSINFO in the Linux section of the system specific config file, along with the corresponding setting of the BASIC_CFLAGS in the Makefile. Add the setting of HAVE_SYSINFO to the cygwin section of 'config.mak.uname'. While here, add a test for the sysinfo() function to the autoconf build system.
