This bug appears to have been reported against 'rawhide' during the Fedora 24 development cycle. Changing version to '24'. More information and reason for this action is here: https://fedoraproject.org/wiki/Fedora_Program_Management/HouseKeeping/Fedora24#Rawhide_Rebase
write.cpp: In member function 'bool mp_real::write(std::ostream&, int, int, int, std::ios_base::fmtflags, int, bool, bool, char) const': write.cpp:199:21: error: no match for 'operator!=' (operand types are 'std::basic_ostream<char>' and 'int') return (s << str) != 0; ~~~~~~~~~~~^~~~ Looks like "Cannot convert 'std::ostream' to 'bool'" in https://gcc.gnu.org/gcc-6/porting_to.html
