Thanks.

However, this has a few drawbacks: a drive letter doesn't have to be 
isascii and a name such as d:foo should also be treated as absolute.  It 
also doesn't support backslashes.

So I would suggest the following:

  #define FILE_NAME_ABSOLUTE_P(NAME) \
      (((NAME)[0] == '/') || ((NAME)[0] == '\\') || \
       (((NAME)[0] >= 'A') && ((NAME)[0] <= 'z') && ((NAME)[1] == ':')))
