Exact. You can define macros like any other macros in C or C++. But you must
tell gcc, that your assembler file should be run at first through the 
preprocessor cpp. This can be done very easy. Instead of calling

gcc -c foo.s

compile it with

gcc -c foo.S

NOTE the upper case 'S'. Or compile it with (if you don't like the uppercase S):

gcc -c -x assembler-with-cpp foo.s

The ending of the line, if it not ends with a backslash.
