It means SIGHUP.

This thread should probably be on the newlib list then.

Isn't that just exactly what you would expect, given that you're talking
about sorting things in ascii order? The period collates very early in ascii
sort order, whereas a lower-case t comes much later; hence if you specify the
'.' you get the makefile at the start of the list instead of the end.

Sounds like it should be quite easy to PPAST then.
