commit 7c414b6bb3f41bc5d72ff2eb60531a4cff5dbd24
Author: Peter Simons <address@hidden>

    Re-format AX_COMPILER_FLAGS_* into canon and bump the #serial numbers.

commit 83c84c32f4c515005571cead4ca39cf6cceca051

    ax_compiler_flags_gir: Add a compiler flags macro for g-ir-scanner
    
    g-ir-scanner is a tool used within a lot of GNOME projects to generate
    introspection data from C APIs. It has a couple of warning flags (and is
    not likely to gain any more in the future), and chaining them to
    --enable-compile-warnings would be useful.
    
    Integrate AX_COMPILER_FLAGS_GIR into AX_COMPILER_FLAGS so that it’s
    enabled by default.

    ax_compiler_flags: Split out into separate macros per tool
    
    Unfortunately, the API for AX_COMPILER_FLAGS does not scale for more
    than two tools, due to the number of parameters required.
    
    Without breaking API, split AX_COMPILER_FLAGS out into:
     • AX_COMPILER_FLAGS_CFLAGS
     • AX_COMPILER_FLAGS_LDFLAGS
    and use both of these in the implementation of AX_COMPILER_FLAGS.
    
    This means that support for a new tool can be implemented as a separate
    macro, and used inside AX_COMPILER_FLAGS if deemed necessary, without
    necessarily needing to add new EXTRA-* parameters for it — if people
    want to add extra parameters for the tool, they can invoke
    AX_COMPILER_FLAGS_* manually.

    ax_compiler_flags: Document approach for locally disabling warnings
    
    Instead of using ‘-Wno-*’ to disable a warning which the compiler is
    erroneously emitting, use #pragmas to disable it for a specific source
    code line.
