Thanks for the work!

Problems I found (on SX-6):
- configure probing for the sizeof(MPI_Offset): linking is done with $CC 
instead of $MPICC. This does not work on SX (don't ask me why; I know it 
should as no MPI function is referenced). This works alright on IA32. Anyway, 
in configure.in, line 245, it should read:
if $MPICC -c conftest.c && $MPICC -o conftest conftest.o ; then
- In the same context, the declaration of 'a' in line 236 can be omitted (our 
compiler gives ugly warning for unused variables. 

Other notes:
- I used the settings as described in README.SX. It seems that the additional 
iteration (calling make again in src/libf after the initial make) is no 
longer necessary, at least not on the system I tested on which was upgraded 
to Super-UX 14.1 from 12.1 in the meantime. As the additional invocation 
causes no harm, we should better leave the README as is.
- Although crossconfiguring does not work (checking for working ftruncate is 
not possible), configuring on the target host and then do a cross-compile 
works fine when setting up necessary aliases on the configure host (cc -> 
sxcc etc.) or vice versa on the compile host (sxcc -> cc). Might be changed 
in README.SX.

Test results for SX: 
_ nf_test: the int1 and int2 tests fail with "value read not that expected" 
for get operations and "Range error: No error" for put operations. I'll have 
to look into this more closely (if it has to do with the fact that integer*1 
is not supported on SX)
- nc_test: passes with the expected two errors 
- nc_test2: fails with a number of errors like this (also fails like this on 
IA32):
        FAILURE at line 637 of util.c: ncmpi_put_vara_text_all: Edge+start 
exceeds dimension bound
I assume this doesn't really matter as only nc_test and nf_test are included 
in the 'testing' target of test/Makefile?

Final note: is the introduction of a ncmpi_delete() function (wrapper for 
MPI_File_delete) still planned?
