gtags under win32

[Mikolaj Sitarz]

Hi,

Few days ago I have sent a question on help-global,  regarding "-f"
option on windows. I was
always getting "Warning: '...path here...' is out of source tree.
(Ignored)"  message when trying use gtags with "-f".
Now I know the purpose of that behavior.  It occurs when the root
directory consists only of a drive letter. Then its sometimes "c:" and
sometimes "c:/". Therefore comparing the paths like "c:/adir" and
"c://adir" failed.
The solution is included in the patch at the end of email.

Patch also contains solution to my second problem. I have dir with
sources mounted over network as a drive letter. When connection
temporary fails - which happens very often - I am getting message
"command failed in xargs_read()" and process exit. Its because of
error on closing the pipe. So I included conditional ignoring error
(based on flag IGNORE_ERROR). Now I can use global which unbelievable
speeds up my work!
Thanks a lot for such great package!
