+@item --with-nonshared-cflags=@var{cflags}
+Use additional compiler flags @var{cflags} to build the parts of the
+library which are always statically linked into applications and
+libraries even with shared linking (that is, the object files contained
+in @file{lib*_nonshared.a} libraries). The build process will
+automatically use the appropriate flags, but this option can be used to
+set additional flags required for building applications and libraries,
+to match local policy. For example, if such a policy requires that all
+code linked into applications must be built with source fortification,
+@samp{--with-nonshared-cflags=-Wp,-D_FORTIFY_SOURCE=2} will make sure
+that the objects in @file{libc_nonshared.a} are compiled with this flag
+(although this will not affect the generated code in this particular
+case and potentially change debugging information and metadata only).
