Quoting Eric Blake: "However, if we have a platform missing strcasestr, then using c_strcasestr as the substitute implementation is probably okay, because that platform would probably be broken in other areas, such as locale support, such that a locale-aware replacement strcasestr would not be worth the effort." Also, depending on the program or library using the fallback GnuLib module, you might not want a version of the function supporting locale, for performance reason or because of the number of dependencies it would bring, and the resulting library size. As an example, on a recent Linux system, importing the strcasestr module generate a library more than twice the size of one importing c_strcasestr. -- Yoann Vandoorselaere | Responsable R&D / CTO | PreludeIDS Technologies Tel: +33 (0)8 70 70 21 58 Fax: +33(0)4 78 42 21 58 http://www.prelude-ids.com
