#os.name reported "QNX"

#java.version reported "1.3.0 subset"
#
#Originally nothing was reported. javac is called j9c and java is called
#j9 with the
#j9 vm. I created symbolic links temporarily to get by that. Currently
#I'm puking when
#it tries to jar things up since j9 doesn't ship with a jar tool. 
#All right. Here is how things stand on porting 2.1 to QNX. (This is were
#I stumble and fall) 
#I decided to try it without any mods initially. It made through
#./configure fine except for
#finding the java include dir. Since we are using j9, the include dir is
#under bin. I set 
#JAVANATINC to point to it in Makefile and then ran make. J9 then puked
#on the -O arg to javac,
#so I removed it. Now it is puking on importing java.awt. What is the
#best way to filter out/
#isolate the gui pieces since I won't be using them on qnx?
