-// Here is the full list of functions that are unified:
-//  strlen, strcmp, stricmp, strncmp, strnicmp
-//  strchr, vsnprintf, strtoul, tolowercase
+// Rename a few common string functions so they are consistent across platforms.
 // tolowercase is like tolower, but not compatible with end-of-file value
 //
 // It's not clear if we will ever use wchar_t strings on unix.  In theory,
 // all strings should be Utf8 all the time, except when interfacing with Win32
 // APIs that require Utf16.
