[Tinycc-devel] warnings w/ tcc-0.9.22 compile

[joe]

Hello list,

When I compiled v. 0.9.21 I found many warnings (Knoppix 3.6 and Mandrake
9.0). I was going to send a mail, then noticed 0.9.22 is out!

So I compiled that (much better), still 1 warning though, and errors in
'make test'. This is on Knoppix 3.6 gcc version 3.3.4 (Debian 1:3.3.4-9).

The below listing captures the screen, from configure, to make, to
'make test'. To avoid long lines I formatted the text so output lines
start on column 3, their continuations prefixed with '+   '.

Hope this helps,

-- Joe
