One can build but not install (or test the build of) the NDBM_File
on FAT filesystems. Installation (or build) on NTFS works fine.
+If one attempts the test on a FAT install (or build) the following
+failures are expected:
+
+ ../ext/NDBM_File/ndbm.t 13 3328 71 59 83.10% 1-2 4 16-71
+ ../ext/ODBM_File/odbm.t 255 65280 ?? ?? % ??
+ ../lib/AnyDBM_File.t 2 512 12 2 16.67% 1 4
+ ../lib/Memoize/t/errors.t 0 139 11 5 45.45% 7-11
+ ../lib/Memoize/t/tie_ndbm.t 13 3328 4 4 100.00% 1-4
+ run/fresh_perl.t 97 1 1.03% 91
+
+NDBM_File fails and ODBM_File just coredumps.
