Ok, I think I somehow "understood" this bug.

Versions before 3.0 didn't have that srs_init.c, with all those EPSG
definitions inside (it's a 110k+-lines file, 4.8M).

After some tries, I found that adding -DOMIT_EPSG=1 to the compilation
commandline made it work on powerpc (I tested it on pescetti).

After some more tries, I saw that it could handle well the calls from
initialize_epsg_00 to initialize_epsg_17: if I de-comment _18 onwards, it FTBFS
as described in the log above. (lines 110432-...)

The same code works fine on i386 (my local machine), I suspect it's some kind
of out-of-memory thing (in fact, passing -DOMIT_EPSG does *NOT* totally skip
those calls, it just doesn't execute them all).

This bug can be solved by passing --disable-epsg at configure-time, but we
would lose some functionality. Probably a better solution exists, but I'm
currently too tired to continue debugging this, will look into it again ASAP.

Frankie, what do you think? Should we disable the "full EPSG initialization"?

Kindly,
David
