Somebody already posted the gcc switch to do that.  But I would like to
point out that what you are doing is non-portable.  Some compilers won't
let you write into constant strings at all, others would result in subtle
bugs.  The reason is that some compilers put constant strings into 
read-only data, where you cannot change anything at run time.

The right thing to do is to copy the strings into automatic arrays (with 
strcpy etc.) and then manipulate them as you see fit.
