No. strcasecmp is specified by POSIX, in <strings.h>. But strcasestr is pure extension, in <string.h>. Also, Bruno added all his mbs* functions in gnulib's <string.h>... > > I think it would be a mistake to encourage gnulib application writers > to rely on <string.h> declaring the nonstandard strverscmp function. > > However, if you can convince the open group to add it for POSIX-201x, > it'd make perfect sense to add it to gnulib's string.in.h now. ...so it looks like Bruno would want to get his mbs* stuff standardized at the same time. At any rate, based on the number of GNU functions standardized in 200x (such as strdup), we stand a chance of being able to pull off additional functions in the next POSIX revision however many years down the road. > > > Besides, fixing it in gnulib will benefit any other package developed primarily > > on Linux but which forgets to include "strverscmp.h".
