That's the default path for Unix; for Windows, I configure with
--prefix=c:/usr (where I've installed various GNU utilities).  However,
there's another problem, since gtags.conf doesn't escape the colon; not
sure where I should handle that - atm you'll have to DIY.  You also need
a patch, so it will compile and build a DLL (Windows needs the -no-undefined
option, not sure how that affects Unix).  BTW, shouldn't terminate_ctags
free argv[1]?

I did have the /usr copied at c:\usr. Since I was running msys from d: drive,

it was prefixing d: into the path. Once I moved it into d:\usr things worked.

I did some modifications to get it working, it looks similar to the patch you shared.

Attached.

Some changes:

   - For some reason, _pgmptr was null. I had to use "GetModuleFileNameA()"

     to make it work. (I am on Windows 7)

   - Had trouble getting the "filter-terminator" arg passed to ctags properly. ctags was getting
     "\n" escaped (\\n) due to which gtags was waiting infinitely. Temporarily I have modified

     ctags to output \n along terminator string. Not sure who is doing the escape.

   - I load ctags.exe from the same location as gtags.exe (something like what we do for

     sort.exe)

Any chance you can include ctags support in your next release?

No, that won't work, as you're building a native tool, so you need a
native path - "c:" instead of "/c" is what you want.  And as mentioned
above, you probably want something for --prefix (which is the only option
I use, but I build with stock MinGW).
