To use libc regexec/regcomp you need to Lets think about even more complex case: file a.c #include <gnu/regex.h> file b.c #include <regex.h> // I.e. system one It breaks GNU regex ABI when calling, say, regcomp() because all _modern_ programs which want GNU regex family assumes that regcomp is part of GNU regex library (or GNU libc) and wants it there. If we remove regcomp() from GNU regex library (like in old variant with NO_POSIX_COMPAT you mentioned), the library will be incomplete and there is no chance for some programs to find needed functions there. I mean - they include <gnu/regex.h> but got wrong (system one) regcomp() in result, if NO_POSIX_COMPAT will be introduced again. -- Andrey Chernov | http://ache.pp.ru/Received on Sat Mar 20 2004 - 04:45:43 UTC
