strptime bugs

[Thorsten Kukuk]

Hi,

According to the LSB test suite and the Austin Draft, our strptime
implementation has some bugs:

strptime("12", "%I", &testbuf) should return tm_hour = 12
The range is [1,12], not [0,11]. But we return tm_hour = 0.

strptime("0091 00 01", "%y %w %W", &testbuf) returns NULL.

strptime("0091", "%y", &testbuf) returns tm_year = 100, but this
should be tm_year = 91.

The leading zeros are allowed.

Adding this test case to our tst-strptime.c showed another bug:
We dereference the strptime result without checking, if NULL was
returned. So our test program seg.faults.
