Hi Bruno

I just had a look at the code (of the library for HP-NonStop), and it does 
indeed look as if they have just been forgotten to get documented and declared 
in in dirent.c, here's the code:

int alphasort(struct dirent **d1, struct dirent **d2)
         return(strcmp((*d1)->d_name, (*d2)->d_name));

int alphasort64(struct dirent64 **d1, struct dirent64 **d2)
         return(strcmp((*d1)->d_name, (*d2)->d_name));

I see that gnulib uses strcoll() rather than strcmp(), which seems to be what 
POSIX mandates.
I'll request a bug fix for these issues from  HP NonStop development...

Bye, Jojo

I'll report this as a bug to HP NonStop development. Last change on the lib was 
that scandir() and scandir64() had been added, looks like alphasort() got added 
too, but not externalized.

Yes, when a function is not documented, it's most reliable to not use it.

Or set the variable ac_cv_func_alphasort to no in your environment or in a 
local config.site file before running configure.
