[trunk/libgfortran/caf/single.c:1468]: (style) Redundant condition:
realloc_need
ed. '!realloc_needed || (realloc_needed && dst_reallocatable)' is equivalent to 
'!realloc_needed || dst_reallocatable'

[trunk/libgfortran/caf/single.c:1923]: (error) Memory leak: single_token
[trunk/libgfortran/caf/single.c:90]: (error) va_list 'args' was opened but not
c
losed by va_end().

#3 I'm not sure about and #4 I know of no architecture where
this matters.
