Presumably CMake then reports something such as
-- Checking for flag: -Wshorten-64-to-32
-- Performing Test WS_C_FLAG_VALID44
-- Performing Test WS_C_FLAG_VALID44 - Failed
in that case, meaning it thinks -Wshorten-64-to-32 isn't supported by the C
compiler?

Presumably CMake then reports something such as
-- Checking for flag: -Wshorten-64-to-32
-- Performing Test WS_C_FLAG_VALID44
-- Performing Test WS_C_FLAG_VALID44 - Success
in that case, meaning it thinks -Wshorten-64-to-32 *is* supported by the C
compiler?
Which version of which compiler is this? (You said "Fedora", so I presume it's
either GCC or Clang; which version of Fedora is it?)
