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.	8 years ago
Pavel Roskin	9091c3eef2	Annotate printf-like functions if supported by the compiler ... Both GCC and Clang support it. Add a macro from Autoconf archive to check for format attribute support.	9 years ago
Pavel Roskin	4da6f8a538	Enable -Wall flag for compilers that support it ... Add Autoconf archive macros to check for -Wall and its dependencies. Adjust m4/.gitignore to only ignore libtool macros. Require Autoconf 2.65 for compatibility with Autoconf archive macros.	9 years ago
Pavel Roskin	2694fa9dac	Create the m4 directory for Autoconf macro files ... Keeping separate files is more maintainable than merging them into a single aclocal.m4 file. It is easier for users to understand where those files come from. Automake knows how to distribute files in the m4 directory.	9 years ago
