According to the man pages on my Ubuntu system, under 'Format of the
format string':

-------------------
If the style using '$' is used, it must be used throughout for
all conversions taking an argument and all width and precision
arguments, but it may be mixed with "%%" formats which do not consume
an argument.

You didn't turn any on...

sfrost(at)tamriel:/home/sfrost> gcc -o qq -Wall test.c
test.c: In function ‘main’:
test.c:5:3: warning: $ operand number used after format without operand number [-Wformat]
