Since the function modifies its argument, the argument type should be char *,
not char const *. Also, the code has an assignment in an 'if' conditional and
the comment is not quite right. Better is:
/* Find the next space in STR, terminate the string there in place,
and return that position. Otherwise return NULL. */
static char *
terminate_at_blank (char *str)
{
char *s = strchr (str, ' ');
if (s)
*s = '\0';
return s;
}

Avoid assignments in 'if' conditionals. Better is:
blank = terminate_at_blank (target);
if (! blank)
continue;
+ if (*source == ' ')
+ {
+ /* The source is an empty string, which is e.g. allowed for
+ tmpfs: "mount -t tmpfs '' /mnt". */
+ *source = '\0';

+ if (! (blank = terminate_at_blank (source)))

Since 'blank' is not used later, surely these 11 lines of code can be simplified
to 2 lines:
if (! terminate_at_blank (source))
continue;
+ int mntroot_s;
+ char *mntroot, *blank, *target, *dash, *fstype, *source;
I suggest using C99-style declaration-after-statement style rather than this
old-fashioned C89-style declarations-at-start-of-block style, just for the
changed part of the code anyway.
