Hi Richy,
If I'm not mistaken, all this should not have broken the ABI on platforms that were already supported, right?
It has broken the ABI, unfortunately. Looking at the changes in the include files, excluding inline functions: - fprintdecimal (std::ostream& stream, unsigned long x) fprintdecimal (std::ostream& stream, long x) no longer exist. - fprintdecimal_impl (std::ostream& stream, uintptr_t x) fprintdecimal_impl (std::ostream& stream, intptr_t x) were added and are used by the new include files. Therefore someone who compiles with the old include files and links with the new library will see link errors (missing fprintdecimal symbols), and someone who compiles with the new include files and links with the old library will see link errors (missing fprintdecimal_impl symbols). fprintdecimal is documented.
