Hi,

It was noticed that the wrong headers were being included for the
generator programs built for the D front-end.  Now COMPILER_FOR_BUILD
and BUILD_COMPILERFLAGS are used to compile them, so that GENERATOR_FILE
will be correctly defined.

Bootstrapped on x86_64-linux-gnu, and committed to mainline.

Regards,
Iain.

gcc/d/ChangeLog:

	* Make-lang.in (DMDGEN_COMPILE): Remove.
	(d/%.dmdgen.o): Use COMPILER_FOR_BUILD and BUILD_COMPILERFLAGS to
	build all D generator programs.
	(D_SYSTEM_H): New macro.
	(d/idgen.dmdgen.o): Add dependencies to build.
	(d/impcnvgen.dmdgen.o): Likewise.
	* d-system.h: Include bconfig.h if GENERATOR_FILE is defined.
