description: Test of nested expansion and refusing macro without arguments
comments: f(2) will expand to 2*g, which will expand to 2*f, and in this
moment f will not be expanded because the macro definition is
a function alike macro, and in this case there is no arguments.
error:
test029.c:34: warning: expression without side effects
test029.c:39: error: redefinition of 'f1'
test029.c:40: error: 'f' undeclared
