It is interesting note, but I don't see how you really can use _both_ GNU regex and libc regexec/regcomp. To use libc regexec/regcomp you need to include our system's <regex.h>, but once you do it, you can't use GNU regex due to headers conflicts. And vice versa, if you include <gnu/regex.h> you can't use regexec/regcomp from libc, because can't include their header, because it produce conflict. So you can either have GNU version of all mentioned functions or system version, but not intermix of them. -- Andrey Chernov | http://ache.pp.ru/Received on Sat Mar 20 2004 - 04:04:22 UTC
