+
+	This patch brings over a few features from MirBSD:
+	* -fhonour-copts
+	  If this option is not given, it's warned (depending
+	  on environment variables). This is to catch errors
+	  of misbuilt packages which override CFLAGS themselves.
+	* -Werror-maybe-reset
+	  Has the effect of -Wno-error if GCC_NO_WERROR is
+	  set and not '0', a no-operation otherwise. This is
+	  to be able to use -Werror in "make" but prevent
+	  GNU autoconf generated configure scripts from
+	  freaking out.
+	* Make -fno-strict-aliasing and -fno-delete-null-pointer-checks
+	  the default for -O2/-Os, because they trigger gcc bugs
+	  and can delete code with security implications.
+
+	This patch was authored by Thorsten Glaser <tg at mirbsd.de>
+	with copyright assignment to the FSF in effect.

++If defined, a function that outputs the assembler code for entry to a
++function.  The prologue is responsible for setting up the stack frame,
++initializing the frame pointer register, saving registers that must be
++saved, and allocating size additional bytes of storage for the
++local variables.  size is an integer.  file is a stdio
++stream to which the assembler code should be output.
++
++The label for the beginning of the function need not be output by this
++macro.  That has already been done when the macro is run.
++
++To determine which registers to save, the macro can refer to the array
++regs_ever_live: element r is nonzero if hard register
++r is used anywhere within the function.  This implies the function
++prologue should save register r, provided it is not one of the
++call-used registers.  (TARGET_ASM_FUNCTION_EPILOGUE must likewise use
++regs_ever_live.)
++
++On machines that have ``register windows'', the function entry code does
++not save on the stack the registers that are in the windows, even if
++they are supposed to be preserved by function calls; instead it takes
++appropriate steps to ``push'' the register stack, if any non-call-used
++registers are used in the function.
++
++On machines where functions may or may not have frame-pointers, the
++function entry code must vary accordingly; it must set up the frame
++pointer if one is wanted, and not otherwise.  To determine whether a
++frame pointer is in wanted, the macro can refer to the variable
++frame_pointer_needed.  The variable's value will be 1 at run
++time in a function that needs a frame pointer.  (see Elimination).
++
++The function entry code is responsible for allocating any stack space
++required for the function.  This stack space consists of the regions
++listed below.  In most cases, these regions are allocated in the
++order listed, with the last listed region closest to the top of the
++stack (the lowest address if STACK_GROWS_DOWNWARD is defined, and
++the highest address if it is not defined).  You can use a different order
++for a machine if doing so is more convenient or required for
++compatibility reasons.  Except in cases where required by standard
++or by a debugger, there is no reason why the stack layout used by GCC
++need agree with that used by other compilers for a machine.
