+Native Toolchain Patches for AdrOS
+====================================
+These patches are needed when building a native GCC/Binutils toolchain
+for AdrOS (Canadian cross: build=x86_64-linux, host=i686-adros, target=i686-adros).
+
+They are applied automatically by build.sh patch functions.

+The declaration in tc-i386.h uses uint32_t but the definition
+used unsigned int, causing a type mismatch error with strict
+cross-compilers.
