Thanks for the fix: all errors are gone, after applying the patch to 
master. There is actually no difference in the profiles (generated by 
gawk/master).

The test program was never meant to be serious gawk code that would go 
into a serious test suite, but if you find it helpful: please take it. I 
just noted that RS is defined twice in the BEGIN clause, which looks 
silly. The first assignment should be dropped. The data file is 
essentially hand-made by myself, following NOAA specs, so it can be used 
without any restrictions.
