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]?

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).
