Russ Rew 79cde861ac Delete obsolete libdiskless directory, replaced by new diskless
implementation.  Deleted obsolete win32, soon to be replaced by Ward's
Windows 32- and 64-bit fixes for building with MSYS/MinGW.  Made
cosmetic cleanup to output of "make check" to make it easier for users
to interpret.  Fixed bug NCF-175: ncdump -t incorrectly interpreting
units attribute (such as "days") without a base time (such as "since
2007-01-01") as a time unit.

Changed name to 4.2.1-beta.
