There was no explicit mention of the platform, but from the word "fink" I
guess it's MacOS X. The report was then already half analyzed in this
thread:
<http://lists.gnu.org/archive/html/bug-gnulib/2010-04/msg00168.html>

The problem appears to be inside gnulib's __mktime_internal. It is still
present after Paul's recent patches: On MacOS X 10.5, after configuring
with CC="gcc -m64", I get:

  000001010000.00 mismatch (-: actual; +:expected)
  --62167132800
  +-62167219200
  000012312359.59 return value mismatch: got 0, expected 1
  FAIL: test-posixtm

Whereas with CC="gcc -m32", I get a different failure:

  skipping 000001010000.00: result is out of range of your time_t
  skipping 000012312359.59: result is out of range of your time_t
