http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48515
Summary: [4.6] GCJ fails to compile jni.cc because of
reflection errors on i686-w64-mingw32 target
Product: gcc
Version: 4.6.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: java
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: blakawk@gentooist.com
When building cross gcj compiler for i686-w64-mingw32 target, libjava fails to
compile with following errors:

This is because in jni.cc, _Jv_JNI_ToReflectedField and
_Jv_JNI_ToReflectedMethod are defined using JNICALL macro, while they are
defined in java/lang/reflect/Method.h and java/lang/reflect/Field.h without.
