Support compile on Illumos based OS (OPenIndiana)

What steps will reproduce the problem?
1. About JDK
$ java -version
java version "1.7.0_60"
Java(TM) SE Runtime Environment (build 1.7.0_60-b19)
Java HotSpot(TM) Server VM (build 24.60-b09, mixed mode)
$ ldd $(which java) # check if 32 or 64 bit version is in use
        libthread.so.1 =>        /lib/libthread.so.1
        libjli.so =>     /usr/jdk/instances/jdk1.7.0_60/bin/../lib/i386/jli/libjli.so
        libdl.so.1 =>    /lib/libdl.so.1
        libc.so.1 =>     /lib/libc.so.1
        libm.so.2 =>     /lib/libm.so.2

2. Prepare Make file
$ grep ^INCLUDES Makefile # added last 2 entries, JAVA_HOME=/usr/jdk/latest
INCLUDES=-I$(JAVA_HOME)/$(HEADERS) -I$(JAVA_HOME)/$(HEADERS)/$(UNAME) 
-I/usr/jdk/latest/include -I/usr/jdk/latest/include/solaris

3. Compile (tried with gcc from distribution and):
$ CC=/usr/gcc/4.7/bin/gcc gmake all
/usr/gcc/4.7/bin/gcc -I/usr/jdk/latest/ -I/usr/jdk/latest//sunos 
-I/usr/jdk/latest/include -I/usr/jdk/latest/include/solaris
