New issue 75 by mack...@gmail.com: src/Makefile.inc.in needs .SECONDARY:  
line
http://code.google.com/p/xar/issues/detail?id=75

What steps will reproduce the problem?

1. autogen.sh, configure & build (should build with -g option)
2. notice the xar.o file was automatically removed as an intermediary  
during the build
3. start gdb on the xar executable that was just built (this is on Mac OS X)
4. gdb complains about missing debugging info

What is the expected output? What do you see instead?

5. Should be able to debug if it was built with -g

What version of the product are you using? On what operating system?

6. Using trunk@232 built on Mac OS X 10.5.8 (and running gdb on there too)

Please provide any additional information below.

7. make normally removes intermediary files during the build.  The way the  
rules are set up in src/Makefile.inc.in results in xar.o being considered  
an intermediary file and so it's normally deleted by make.  On Mac OS X  
(and possibly others) the needed debug information is stored in the .o and  
so debugging fails.

8. The following patch (also attached) to src/Makefile.inc.in corrects the  
problem by telling make to retain the intermediary .o file:

9. After the above patch, builds leave the intermediary file xar.o alone  
and debugging succeeds.
