Hi Xypron,

yes, swapping the files leads to problems. For example when using the .jar 
generated on the Linux machine on my Mac OS X laptop, I get the following 

Exception in thread "main" java.lang.UnsatisfiedLinkError: 
        at org.gnu.glpk.GLPKJNI.GLP_BR_PCH_get(Native Method)
        at org.gnu.glpk.GLPKConstants.<clinit>(

This is glpk 4.43 and glpk-java 1.0.13. I think the same error occurs on the 
Linux machine when using the .jar generated on the Mac laptop (I'm not at work, 
so I can't post the exact error message right now). 

They also have different file sizes:

-rw-r--r--   1 fabio  staff    49K 31 May 19:18 linux64-glpk-java.jar
-rw-r--r--   1 fabio  staff    43K 31 May 19:18 mac64-glpk-java.jar
