I've built 1.14 on IRIX 6.5 with the SGI C compiler. Running the
testsuite reveals the following failure:
$ gtar zxf gsl-1.14.tar.gz
$ cd gsl-1.14
$ ./configure --enable-static --enable-shared
$ gmake
$ gmake check

Thanks for the bug report. I don't have any solution to that. If you
can see the cause and send a patch I will apply it. The bigsparse test
was added in 1.14 so it may not be due to any change in the code.
