Nope. Depending on the software authors/company I usually trust software until it breaks things (I'm only a human, too ;-)). > I remember a similar discussion years ago in comp.unix.solaris > where people claimed that GNU sort was faster than Solaris sort. > It turned out that GNU sort did not sopport anything than LC_ALL=C. > After Paul Eggert did enhance GNU sort to behave correctly, it was > much slower than Solaris sort and Paul did ask Sun to make it OSS. That's interesting - thanx for the info. BTW: I don't think, that the GNU libc uses the GNU regex usually bundled with many opensource software/downloadable via ftp.gnu.org/... Last time (year ago?), when I had a look at GNU regex, I didn't consider it for more evals after finnishing the first round...
