'Regex.h' not found problem when compiling user program under Visual Studio 2005

Hello everyone,

I am new here and is working on libwww for part my project.

I tested it successfully through ubuntu with the sample code 'showlinks.c'.

However while I ported the same code to windows, and trying to compile showlinks.c in Visual Studio, I got
following error:

------------------------------------------------------------------------
fatal error C1083: Cannot open include file: 'regex.h': No such file or directory    c:\documents and
settings\administrator\Desktop\w3c-libwww-5.4.0\w3c-libwww-5.4.0\library\src\wwwsys.h    1138   

------------------------------------------------------------------------

I already installed libwww through binary, downloaded source code to my desktop with extraction and
import header files through <property>-<link>  in Visual Studio.  I searched for that 'regex.h' file and
it is really not there,  I am not sure what is missing there, do I have to install something else ? 

Any help is well appreciated,

Thanks,

-Kun

Yes, various flavors of linux seem to have little issue with regular
expression libraries, since it is part of the glibc.  For example under
fedora core 10, we have,

  $ rpm -qf /usr/include/regexp.h
  glibc-headers-2.9-3.x86_64

Where as my a debian system might show,

  $ dpkg-query -S "/usr/include/regexp.h""
  libc6-dev: /usr/include/regexp.h

What is your preferred choice of libc implementations under windows ?
