[Openmcl-devel] ccl-1.11 compilation failure

[Andrey G. Grozin]

Hello *,

I've tried to recompile ccl-1.11 from sources on my Gentoo Linux 64-bit 
box, but I got

x86_64-pc-linux-gnu-gcc -include ../platform-linuxx8664.h -c ../image.c 
-DLINUX -D_REENTRANT -DX86 -DX8664 -D_GNU_SOURCE -DHAVE_TLS 
-DSVN_REVISION="unknown"  -g -O2 -Wno-format -m64 -o image.o

Any idea what can this mean? I successfully compiled the same ccl-1.11 on 
this box earlier, so, it might be a result of some library or compiler 
upgrade.
