Yes, true, though the version in my branch (which itself is becoming outdated) 
is 1.2.4. There was a problem with libpng 1.4.4 that didn't find zlib and I 
thought it was because of this "old" version of it (because recompiling 1.2.5 
fixed it). But in reality the problem stems from the "z_" prefix added to each 
function in the RTEMS zlib, which isn't there when recompiling the vanilla 
zlib (and yes, I still want to remove it, as it is less painful than fixing 
libpng's auto*** scripts). I forgot to update the reason on the wiki, thanks 
for pointing this out.

Sebastian spoke on IRC about this problem already, and might fix libpng's 
configure script. So hopefully the zlib recompilation won't be needed at all.

Doesn't that flag mean "turn whatever optimizations on", which, with the 
current versions of GCC, is an alias for -O3?
