after the update of netcdf to 4.3.1 bootstrap fails because of the double call to AM_INIT_AUTOMAKE in configure.ac lines 39-40.
in 4.3.0 the first of the 2 call was commented out, and indeed this fixes it also for 4.3.1.
i am no expert of autotools, however, so i'm not sure this is ok.
fix for #194 - bootstrap fails with automake 1.14.1
Gah - I forgot to remove the original line when I added the workaround.
Fixed in ce88e40.
