diff between the original time_.h file and one that compiles

Hi I could not compile gs 9.04 (either from the git repository or from the sourceforge tar.gz)
I think that the error I get might depend on the presence of sys/time.h on my system.
Surrounding the struct definition with an "#ifndef _BITS_TIME_H" I was able to compile, but not being an expert I am not sure it is the most correct thing to do.
I am attaching a diff file and the config.log.



The detailed error was:

It seems some distributions have moved time.h, which confuses the build.

For now you can compile successfully by doing:
./configure
make XCFLAGS=-DHAVE_SYS_TIME_H=1

And we'll track the problem under the existing bug report.
