Ok, let's see what gcc sees. You're telling it to search directories
/install/jdk1.1.8/include and /install/jdk1.1.8/include/win32 for
jdk includes. So far so good.

Now note the problem here. There are no signs of either of the jdk
include directories!

Nor are they here, which would be the case normally if the paths were

I really don't have a clue, sorry. Can you do a 
  $ cat /install/jdk1.1.8/include/<SOME_FILE_NAME>
