clib2 Code

- We now allocate the AnchorPath used in the unistd_wildcard_expand.c
code. Also, the contents of the AnchorPath structure are no longer
modified between calls. MatchEnd() has to be sufficient.

- Folded duplicate code in "time_mktime.c"; also, errno is no longer
modified unless the library is built with the "CHECK_FOR_NULL_POINTERS"
option.

- Updated the ".cvsignore" file.

- Moved the date/time conversion test code around in "test.c".

- The functions in stdlib.h which require a compiler that supports the
"long long" data type are no longer prototyped if the library is built
for SAS/C.

- Folded duplicate code stdio_init_exit.c into a common function.

- Simplified the code in time_asctime_r.c which builds the time
string. It gracefully handles buffer sizes which are too short
by returning an empty string.

- Moved the tm->tm_wday initialization out of the hook function
in time_strftime.c since it was to be called only once anyway.

- Lost a few compiler warnings in unistd_time_delay.c and
time_gettimeofday.c.

- Folded duplicate code in time_mktime.c; also, errno is no longer
modified unless the library is built with the CHECK_FOR_NULL_POINTERS
option.

This commit was manufactured by cvs2svn to create tag 'V1_187'.

- Added the missing 'time_convert_time.c'.

- Changed the algorithm that calculates the number of days that have passed
so far as used by the the __convert_time() function and the conversion
code in strftime().

- Also changed the algorithm used by strftime() to produce the week numbers
(the '%U' and '%W' format specifiers). The new method is much simpler
than the old one.

- Made the code that converts a 'time_t' value into the 'struct DateStamp',
as used by strftime() and utime(), into its own function. This also
fixes a bug in the code strftime() would use which was completely
unaware of the local time zone settings.

- We also test the strftime() %U, %W and %j format specifiers.

- Plugged in a different algorithm for calculating the day of the week in
strftime() and asctime_r(). This one isn't sensitive to the effects of
adding/subtracting the local time zone.
