execing 'gcc' from within Java application

[MNewcomb@tacintel.com]

GCC 3.0.3

I have a set of classes that use JNI.  I was using make to build them.  I am
switching to Ant.  When Ant (a Java process) execs off gcc, gcc totally
screws with my JNI code.  It starts replacing all my jobject and jstring
variables with java::lang::Object and java::lang::String.

It is just happening when I invoke gcc from within ant.  I check the command
line from Ant and it's the exact same thing.  In fact, I cut and paste from
Ant output to an xterm and everything compiles fine.

So, how do I tell gcc to just compile the code?

Thanks,
Michael
