The fgetround test produces the following

rounding using to-nearest rounding:
rint (2.3) = 2.0
rint (3.8) = 4.0
rint (-2.3) = -2.0
rint (-3.8) = -4.0

The latest patch fixes the rounding errors on i686. And now it passes
all of the tests for all of the architectures that the build process
tests on.

I am happy to continue testing things here as well though.

One of the pull request moderators has patched libdivecomputer because
when building for musl some dive computers were showing warnings

oceanic_common.h:31: warning: "PAGESIZE" redefined
   31 | #define PAGESIZE 0x10
