Did the code crash when there were negative temperatures using the old
function?
BYTE data = BYTE_MASK((int) (T + .49)); // round off

I only used that for a quick fix to a problem connected with the 1821
returning negative temperatures and causing a crash. I agree that it's not
worth creating a dependency for so I would be happy to code it into the 1821
support if you give me a few days to code and test.

We have to make some more changes in configure.ac after lrint() is used in
ow_1821.c. This function is located in libm.so, and this is the first
dependency to this library.
I think it's a waste of memory to add a new dynamic library if we only use
one single function in it from owlib.. Especially on the embedded systems.
Anyway. the dependency could be added with this row in configure.ac.
AC_SEARCH_LIBS(lrint, m, AC_DEFINE(HAVE_LRINT, 1, [Define if you have
lrint]))
I have added some changes in the CVS to make this check.
