<dt><code>Environment Variables</code></dt>
<dd><p>Meson supports the standard CC and CXX environment variables for
changing the default compiler, and CFLAGS, CXXFLAGS, and LDFLAGS for setting
-options to the compiler and linker.
+options to the compiler and linker during the initial configuration.
-The default compilers depends on your operating system. Meson supports most of
-the popular compilers, a complete list is available
-<a href="http://mesonbuild.com/Reference-tables.html#compiler-ids">here</a>.

-These arguments are consumed and stored by meson when it is initialized or
-re-initialized. Therefore passing them to meson configure will not do anything,
-and passing them to ninja will only do something if ninja decides to
-re-initialize meson, for example, if a meson.build file has been changed.
-Changing these variables will not cause all targets to be rebuilt, so running
-ninja clean is recommended when changing CFLAGS or CXXFLAGS. Meson will never
-change compiler in a configured build directory.
+These arguments are consumed and stored by meson when it is initialized. To
+change these flags after the build is initialized (or when doing a first
+initialization), consider using <code>-D${lang}_args</code> and
+<code>-D${lang}_link_args</code> instead. Meson will never change compiler in a
+configured build directory.
