Dave, in this part of the path_addcomp() code
for(pp=first; pp; pp=pp->next)
{
if(len <= strlen(pp->name) && memcmp(name,pp->name,len)==0 &&
(pp->name[len]==':' || pp->name[len]==0))
{
pp->flags |= flag;
return(first);
}
}
why is there a check for ':' ? optimization because it may be part of $PATH
from the env?
is (pp->name[pp->len] == 0 || pp->name[pp->len] == ':') always true?
if so then would this work:
for(pp=first; pp; pp=pp->next)
if(len == pp->len && memcmp(name,pp->name,len)==0)
{
pp->flags |= flag;
return(first);
}
