+
+   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++ .
+
+
+   Patches order:
