Cast sizeof() to (int), as it's being compared against an int, not a size_t. If i is changed to a size_t, it means the logic must be slightly changed later in the flow, where --i is checked to be >= 0. I am not sure I want to make a logic change to account for clearing up a warning, when an aesthetic one will keep from modifying the logic. Other harmless casts, that I think I've made in the right directions. Make gpbc() an inline function, rather than an obfuscated macro, make its scratch space local, rather than global. The previous macro used a dirty hack (logical AND in place of a conditional) which would lead GCC to throw a fit (rightly so) as the logical check, as well as the incrementation of a variable, were not used for anything. const'ify a few places where gcc3 yells. xstrdup() some global consts in places where we xstrdup() when not using consts, but tried to assign them to non-consts before. Don't use execv(2) if we don't have the kind of arguments it wants. Reviewed by: asmodai obrien tjr Submitted by: tjr (a gcc3 build log)
