            Bug ID: 61552
           Summary: Unneeded check for libart
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: java
          Assignee: unassigned at gcc dot gnu.org
          Reporter: Arfrever.FTA at GMail dot Com

According to my grepping, libart was actually used only in GCC 3.4.* and 4.0.*
(e.g. libart headers were included in GCC's
libjava/jni/gtk-peer/gnu_java_awt_peer_gtk_GtkImagePainter.c).

libjava/configure.ac in GCC trunk still contains:

      PKG_CHECK_MODULES(LIBART, libart-2.0 >= 2.1)
      AC_SUBST(LIBART_CFLAGS)
      AC_SUBST(LIBART_LIBS)

No Makefile.am file uses LIBART_CFLAGS or LIBART_LIBS.
4 generated Makefile.in files contain useless assignments of LIBART_CFLAGS and
LIBART_LIBS.

$ grep -E "LIBART_(CFLAGS|LIBS)" **/Makefile.am
$ grep -E "LIBART_(CFLAGS|LIBS)" **/Makefile.in
libjava/gcj/Makefile.in:LIBART_CFLAGS = @LIBART_CFLAGS@
libjava/gcj/Makefile.in:LIBART_LIBS = @LIBART_LIBS@
libjava/include/Makefile.in:LIBART_CFLAGS = @LIBART_CFLAGS@
libjava/include/Makefile.in:LIBART_LIBS = @LIBART_LIBS@
libjava/Makefile.in:LIBART_CFLAGS = @LIBART_CFLAGS@
libjava/Makefile.in:LIBART_LIBS = @LIBART_LIBS@
libjava/testsuite/Makefile.in:LIBART_CFLAGS = @LIBART_CFLAGS@
libjava/testsuite/Makefile.in:LIBART_LIBS = @LIBART_LIBS@

I suggest to delete check for libart in 
libjava/configure.ac and regenerate appropriate Makefile.in files.
