1gengtype is generated for both the build system and the target. -DGENERATOR_FILE
2was added in the patch http://gcc.gnu.org/ml/gcc-patches/2012-07/msg00273.html
3and was applied to both versions of gengtype.

5Unfortunately the presence of this flag triggers the build configuration (bconfig.h)
6to be included for the target build of gengtype. Compiling gengtype with the target
7compiler and bconfig.h can result in errors if the build and target systems are
8dissimilar. An example case this fails is cross compiling gcc on linux for a darwin
9target system:

16which occurs since auto-build.h and auto-host.h have differnet values of
17HAVE_FPUTC_UNLOCKED:

19#define HAVE_FPUTC_UNLOCKED 1
20/* #undef HAVE_FPUTS_UNLOCKED */
21
22The obvious fix is to only include the flag on build/ targets which this patch does, however
23this also leads to compile errors due to const_tree being undefined but used in double_int.h
24
25I added a GENERATOR_FILE2 flag to workaround those in the
26target case and allow the build to succeed.

28Only the build/gengtypes should have the -DGENERATOR_FILE
