Hello,

this patch fixes some issues in libjava for windows targets.  It
addresses for now only 32-bit target, but for JNICALL definition I
introduced already logic for 64-bit windows target too as preparation.
One nit remains, but I am not quite sure how to approach it. In
ltmain.sh it is necessary to set valid_a_lib to yes, so that a
complete build is possible. This is a libtool issue and maybe Ralf
could take care here. If I understand correct, here should be module
instead of library used. But well, Ralf might know better.

ChangeLog

2011-04-05  Kai Tietz

	* configure.ac (libgcj_ld_export_all): Set for windows
	native targets to export-all-symbols.
	(LIBGCJ_LD_EXPORT_ALL): Export libgcj_ld_export_all.
	* Makefile.am (libgcj_la_LDFLAGS): Add LIBGCJ_LD_EXPORT_ALL.
	* sysdep/i386/backtrace.h (MAIN_FUNC): Define for windows
	native targets to DllMain.
	* gcj/javaprims.h (JNICALL): Define it dependent
	for different windows targets.
	* include/jni_md.h: Likewise.
	* java/lang/Class.h (_Jv_JNI_ToReflectedField): Mark
	JNICALLS for friends.
	(_Jv_JNI_ToReflectedMethod): Likewise.
	* java/lang/reflect/Field.h (_Jv_JNI_ToReflectedField):
	Likewise.
	* java/lang/reflect/Constructor.h (_Jv_JNI_ToReflectedMethod):
	Likewise.
	* configure: Regenerated.
	* Makefile.in: Regenerated.
	* include/Makefile.in: Regenerated.
	* testsuite/Makefile.in: Regenerated.
	* gcj/Makefile.in: Regenerated.

Tested for i686-w64-mingw32. Ok for apply?

Regards,
Kai

Most of this seems ok to me.

These headers are generated.  You have to edit headers.txt and then
rebuild them.

Hi Tom,

I added to headers.txt the changes and regenerate headers.  Btw it is
a bit tricky to enable for libjava the maintainer-mode and then have a
successful configure for it ...

ChangeLog

2011-04-06  Kai Tietz

	* configure.ac (libgcj_ld_export_all): Set for windows
	native targets to export-all-symbols.
	(LIBGCJ_LD_EXPORT_ALL): Export libgcj_ld_export_all.
	* Makefile.am (libgcj_la_LDFLAGS): Add LIBGCJ_LD_EXPORT_ALL.
	* sysdep/i386/backtrace.h (MAIN_FUNC): Define for windows
	native targets to DllMain.
	* gcj/javaprims.h (JNICALL): Define it dependent
	for different windows targets.
	* include/jni_md.h: Likewise.
	* headers.txt (_Jv_JNI_ToReflectedField): Mark
	JNICALLS for friends.
	(_Jv_JNI_ToReflectedMethod): Likewise.
	* java/lang/Class.h: Regenerated.
	* java/lang/reflect/Field.h: Regenerated.
	* java/lang/reflect/Constructor.h: Regenerated.

	* Makefile.in: Regenerated.

Ok for apply?
