Hello,

The make_temp_name function in a case when BASE64_P is true or when
HAVE_LONG_FILE_NAMES is
not defined builds buffer where first three characters is a PID in
base64 encoding. This leads to some of
code duplication.

Attached patch introduces make_temp_name_buf() function which will do
this functionality and allows to avoid
code duplication.

Thank you

Following recent changes to the make-temp-name and related functions,
this patch is no longer applicable.
