Tvheadend

I'm trying to build the latest git on a VM (using an old gcc, I know, but I need to use this one) but it fails with the errors below.

Thread model: posix
gcc version 4.3.2 (Debian 4.3.2-1.1)

Note that adding --disable-zlib option does not change anything (same error).
On another system with newer gcc it works, of course, but I need to build TVHeadend on this one.

Have you got any suggestions?
Thanks.
