Make or Makefile problem?

[Neale Ferguson]

I¹m building icedtea6-1.4.1 and am encountering the following error:


/bin/mkdir -p 
/home/neale/icedtea6-1.4.1/openjdk-ecj/control/build/linux-s390x/tmp
rm -f 
/home/neale/icedtea6-1.4.1/openjdk-ecj/control/build/linux-s390x/tmp/rt-orig
.jar
ifneq (,1)
/bin/sh: -c: line 0: syntax error near unexpected token `,1'
/bin/sh: -c: line 0: `ifneq (,1)'
make[2]: *** 
[/home/neale/icedtea6-1.4.1/openjdk-ecj/control/build/linux-s390x/tmp/rt-ori
g.jar] Error 2
make[2]: Leaving directory `/home/neale/icedtea6-1.4.1/openjdk-ecj/jdk/make'

It appears due to this part of the recipe:

$(RT_JAR): $(if $(JAR_KNOWS_ATFILE),$(RT_JAR_FILELIST),$(RT_JAR_ARGLIST)) \
    $(JAR_MANIFEST_FILE)
        $(prep-target)
ifneq (,$(JAR_KNOWS_ATFILE))
        (cd $(CLASSBINDIR) && \
        $(BOOT_JAR_CMD) c0mf $(JAR_MANIFEST_FILE) $@ \
            $(JAR_JFLAGS) @$(RT_JAR_FILELIST))
else
:

I'm using GNU make 3.81.
