   If you build gmp/mpfr/mpc inside of gcc source tree; then you have to apply following patches:

     gcc-12.2.0-fixinc-gmp-inside.patch
     gcc-12.2.0-gmp-inside.patch

   If you use system installed gmp/mpfr/mpc, then you have to apply other patches:

     gcc-12.2.0-fixinc-gmp-outside.patch
     gcc-12.2.0-x86_64-multilib.patch

   libcpp:
   ======
     gcc-12.2.0-build-libcpp.patch - is needed when build != host machine for avoid error related to
     pass target CFLAGS to the build compiler.
     NOTE:
     ----
       The patch 'gcc-12.2.0-build-libcpp.patch' should be applyed strongly after
       the 'gcc-12.2.0-gmp-inside.patch'.


   Ada CCACHE:
   ==========
     gcc-12.2.0-ccache-ada.patch - gnatmake/gnatlink not correct parses --GCC="..." options
                                   If you will use --GCC="ccache gcc --someflags" then these
                                   utilites deside that CC=ccache and CFLAGS="gcc --someflags".
                                   This patch created especialy for building ada/tools without
                                   ccache in case when whole build system uses ccache as well.
                                   If you applay this patch then you have to export two variables
                                   from your Makefile (which builds GCC):

                                     export GCC_FOR_GNAT      = $(CROSS_COMPILE)gcc --sysroot=$(TARGET_DEST_DIR)
                                     export GCC_LINK_FOR_GNAT = $(CROSS_COMPILE)g++ --sysroot=$(TARGET_DEST_DIR)

                                   without $(CCACHE) before $(CROSS_COMPILE)gcc/g++ .
