AS I wrote previously the above changeset gives a link error for building on 
3.2.3RC1 sources like 

Creating library file: liboctave.dll.a
fu008091.o:(.idata$2+0xc): undefined reference to `libmoldname_a_iname'
nmth008090.o:(.idata$4+0x0): undefined reference to `_nm__tzname'
collect2: ld returned 1 exit status
make[2]: *** [liboctave.dll] Error 1
make[2]: Leaving directory `/home/octaves/OctBuild/octave-3.2.3-rc1/liboctave'
make[1]: *** [liboctave] Error 2
make[1]: Leaving directory `/home/octaves/OctBuild/octave-3.2.3-rc1'


I looked the source strftime.c in liboctave.
The above errors the GCC-4.4.0 + MinGW -offcial seem to be treat code related 
to 'tzname' in MinGW
libraries.  So I modified condig.h to be the flag HAVE_TZNAME disable after 
configure like

/* Define to 1 if you don't have `tm_zone' but do have the external array
   `tzname'. */
//#define HAVE_TZNAME 1

With the above, the link error disappeared and I can get successful results on 
the octave prompt, 

octave.exe:3> strftime ("%e %T", localtime (time ()))
ans = 30 15:37:45

*******************
The errors
fu008091.o:(.idata$2+0xc): undefined reference to `libmoldname_a_iname'
nmth008090.o:(.idata$4+0x0): undefined reference to `_nm__tzname'

Perhaps comes from the fault of the GCC-4.4.0 on MinGW-Official.
I will ask the above problem at the MinGW Mailing list.

Anyway it is pleasure for me the changeset 9424 itself can be applied to the 
environment for GCC-4.4.0
MinGW-Official.

The results of the inquiry on the MinGW ML will be reported in the Octave-ML 
list.
