The failures occur because the int-conversion and incompatible-pointer-types warnings are treated as errors. According to https://gcc.gnu.org/gcc-14/porting_to.html#warnings-as-errors, these warnings are treated as errors in gcc-14, but were treated as warnings by default in gcc-13 and earlier. I find that bitshuffle compiles and installs without issue in gcc-13. Altering the lines reference above should be sufficient to restore gcc-14 compatibility.
