+ * genconditions.c (write_header): In generated code, #ifdef out
+ all includes and fake declarations, except includes of bconfig.h
+ and system.h, unless GCC_VERSION >= 3001. Do not include
+ gensupport.h in any case.
+ (write_conditions): Generate a definition of struct c_test. Add
+ a comment to the generated #endif.
+ (write_one_condition): Escape backslashes in string too.
+ (write_writer): Generated code must escape backslashes and quote
+ marks (but not newlines) in the strings it writes.
+ * Makefile.in (build/gencondmd.o): Update dependencies.
