[Bug-gsl] [bug #43258] confluent hypergeometric functions

[Patrick Alken]

Follow-up Comment #3, bug #43258 (project gsl):

Thanks for reminding me about the testing.  I fixed the Confluent 
Hypergeometric U() errors for my tests; but neglected to revise 
test_hyperg.c by killing the U() fixme's.  I have now done that and the 
tests all succed for U().  I will send you the modified test_hyperg.c; 
the other file hyperg_U.c  is unchanged.  It should be reviewed and 
double checked on another system.  If it passes then somebody can take 
out the "fixme" for U() permanently.
I have done nothing for M() except try to find out where the egregious 
errors are and understand them.  I haven't even figured out how to fix 
the thing I mentioned below; I will probably try killing the Kummer 
Transform and see how bad the regular summation is with x<0 ; otherwise ...
