You can use inline for C code.  Check out the gcc manual at http:// 
gcc.gnu.org/onlinedocs/gcc-3.4.3/gcc/Inline.html

In gcc 3, the inlined function's definition (body) must be before any  
calls to the inlined function in your source file.  Based on a  
comparison between version 3.3 and 4.0 of gcc for PowerPC, it looks  
like version 4.0 of gcc is quite a bit smarter about what to inline  
when the "inline" modifier is used, and doesn't require the  
definition to be before all uses.  The PowerPC 4.0 version does what  
you expect it to do -- I'm assuming the 4.0 avr version behaves the  
same way.
