As an example:
jirka@omelette:/tmp> echo "__int128 i;" > test.c
jirka@omelette:/tmp> gcc -o test -m64 test.c
/usr/lib64/gcc/x86_64-suse-linux/4.8/../../../../lib64/crt1.o: In function
`_start':
/home/abuild/rpmbuild/BUILD/glibc-2.18/csu/../sysdeps/x86_64/start.S:118:
undefined reference to `main'
collect2: error: ld returned 1 exit status
jirka@omelette:/tmp> gcc -c -m64 test.c
jirka@omelette:/tmp> echo "__int128 i;" > test.c
jirka@omelette:/tmp> gcc -c -m64 test.c
jirka@omelette:/tmp> gcc -c -m32 test.c
test.c:1:1: error: â__int128â is not supported for this target
__int128 i;

jirka@omelette:/tmp> gcc --version

So it works for x86_64 64-bit target, but not for 32-bit target.
And I mean I would like to have this functionality in all 32-bit and 64-bit
targets, not just in some. Since I'm developping a cross-platform network stack
which runs on Intel (32-bit, 64-bit), PowerPC (32-bit), Itanium (64-bit), ARM
(32-bit), MIPS (32-bit), etc.
