[PATCH] translate capitalized functions in create_stubs

Hi When we use prototype files for ext_skel, we noticed that a function name with capital letters doesn't work properly since php extension must have lowercase function names. However, ext_skel doesn't warn or fix an erroneous prototype file. Here's a small patch to the create_stubs file which will both warn users that a function name from the prototype file contains capital letters, and it will lowercase the function name. Out of curiosity, why ext_skel/create_stubs a shell/awk script? Were it written in perl, Windows users could use it too. Is there a design reason for shell/awk or is it just historical? dave
