Bug#1023821: Compile with -DZFP_BIT_STREAM_WORD_SIZE=8 ?

[Enrico Zini]

Source: zfp
Version: 1.0.0-2
Severity: normal

Hello, and thanks for packaging zfp!

I've been trying to build hdf5-zfp[1] in Debian, and it requires[2] zfp
to be built with BIT_STREAM_WORD_SIZE=8. Indeed, while CMakeLists.txt
defaults it to 64, the FAQ recommends setting it to 8 to have portable
files[3].

I did verify that after adding -DZFP_BIT_STREAM_WORD_SIZE=8 to
dh_auto_configure in zfp's debian/rules and rebuilding the package,
tests for hdf5-zfp pass.

Would it make sense to change the default to 8?
