Neither strrev() nor itoa() are part of ANSI C, as far as my copy of Plauger & 
Brodie's Standard C inform.  

Both can be easily written in C.  It is possible that the versions in the VC
library were written in optimized x86 assembly.  But if you don't use them
very often, the performance lost is negligible.
