The fix is to change /usr/lib/python2.5/site-packages/aotcompile.py,
which doesn't put the right pathnames into the object files.

I've attached a patch.  gbenson, please look this over.  This is my
first ever Python hack, so You Have Been Warned.  Input about my
(doubtless execrable) Python style welcome.

I have tested this patch on writer2latex, and I can debug it:


(gdb) b 'writer2latex.Application.main(java.lang.String[])void'
Function "writer2latex.Application.main(java.lang.String[])void" not defined.
Make breakpoint pending on future shared library load? (y or [n]) y

(gdb) r -jar /usr/share/java/writer2latex.jar
Starting program: /usr/bin/gij -jar /usr/share/java/writer2latex.jar

...

Breakpoint 1, writer2latex.Application.main(java.lang.String[])void (
    args=@2aaaaaafcf40)
    at /usr/src/debug/writer2latex05/source/writer2latex/Application.java:110
110                 Application app = new Application();
(gdb) n
111                 app.parseCommandLine(args);
(gdb) s
writer2latex.Application.parseCommandLine(java.lang.String[])void (
    this=@2aaaaf891e60, sArgs=@2aaaaaafcf40)
    at /usr/src/debug/writer2latex05/source/writer2latex/Application.java:466
466                 if (sArg.startsWith("-")) { // found an option
(gdb) 
471                     else if ("-xhtml+mathml+xsl".equals(sArg)) { sTargetMIME = MIMETypes.XHTML_MATHML_XSL; }
(gdb) 
466                 if (sArg.startsWith("-")) { // found an option
(gdb) 
471                     else if ("-xhtml+mathml+xsl".equals(sArg)) { sTargetMIME = MIMETypes.XHTML_MATHML_XSL; }
(gdb) 
464             while (i<sArgs.length) {
(gdb) 
506             if (sSource==null) {
(gdb)
