Simple concatenations like
str = str."foo"
generate 3 strcpys and a strcat.
x = 5
first copies 5 to a temporary variable then sets x to the temporary variable.
x++
copies 1 to a temporary variable then copies x to a temporary variable, then
adds the two temp and sets x to that,
Is there anything that can be done to make this more efficient?
