BTW, I'm sorry I've been unable to assist in this for quite a while,
it's been (and still is) very busy with customer deliveries in my day
job. It'll get better soon though.

I've tried the above options with icc 9.0, 9.1 and 10.0, all of the
compilers accept it fine:

/opt/intel/compiler_100_026/bin/icc -no-ansi-alias -fp-model precise
-std=gnu89 -we 140,147,165,266 -wd 279,981,1469 -o hello hello.c
echo $?
0
 ./hello
Hello

That works fine too:

/opt/intel/compiler_90_031/bin/icc -no-ansi-alias -fp-model precise
-std=gnu89 -we 140,147,165,266 -wd 279,981,1469 -g -o hello hello.c
./hello
Hello
/opt/intel/compiler_90_031/bin/icc -no-ansi-alias -fp-model precise
-std=gnu89 -we 140,147,165,266 -wd 279,981,1469 -O0 -o hello hello.c
./hello
Hello
