Pavel Roskin	a680d46edf	Use -Wwrite-strings compiler flag if supported, add required macros ... String literals are const in C++. Using this warnings moves us closer to the stated goal of C++ compatibility, makes the code cleaner and lets compilers optimize the code better. Add m4/ax_append_compile_flags.m4 from Autoconf Archives for the AX_APPEND_COMPILE_FLAGS macro and m4/ax_check_compile_flag.m4 as its dependency.	9 years ago
