Compiling thunar-vfs-1.1.0 on Solaris fails with:

  CC     libthunar_vfs_1_la-exo-mount-point.lo
exo-mount-point.c:323:2: #error "Add support for your operating system here."
exo-mount-point.c:427:2: #error "Add support for your operating system here."

The relevant code ought to be picked up:

#elif defined(HAVE_GETMNTENT)

however, HAVE_GETMNTENT isn't defined.

The code works fine in exo-0.3.107, which does define HAVE_GETMNTENT.

It appears the check for getmntent is missing from configure.

(Manually adding the #define to config.h fixes the problem.)
