FUNCTION
bfd_get_unique_section_name
SYNOPSIS
char *bfd_get_unique_section_name(bfd *abfd,
const char *template,
int *count);
DESCRIPTION
Invent a section name that is unique in @var{abfd} by tacking
a digit suffix onto the original @var{template}. If @var{count}
is non-NULL, then it specifies the first number tried as a
suffix to generate a unique name. The value pointed to by
@var{count} will be incremented in this case.
