I am getting a bug report https://github.com/leoliu/ggtags/issues/121
because emacs and global represent paths in cygwin differently?
global: "/e/gtk-3-compilation/build/gtk+-3.19.4/gtk/"
emacs: "e:/gtk-3-compilation/build/gtk+-3.19.4/gtk/"
Which path representation is more correct? Do we have something to
convert one to the other?
Thanks,
Leo

The answer is "use Cygwin port of emacs under Cygwin".
You could try to support Cygwin paths in Windows Emacs, but I don't know
if that's worth the value.
There are some path conversion functions in Cygwin Emacs (probably not
in Window Emacs), but they weren't available in the last release I used
on Cygwin.

Neither, AFAIK. Cygwin file names look like /cygdrive/e/gtk-3-...
What you show looks like MSYS format, not Cygwin format. This is
consistent with what the OP says about invoking 'global' in
"mingw32.exe window".
In sum, I think the OP should use a consistent set of tools, instead
of mixing subtly incompatible sets. My guess is that his 'global' is
an MSYS application or script, not a native Windows port, whereas his
Emacs is a native build. These don't mix too well.
We have the unmsys--file-name function which might help, but I see no
reason why you as a maintainer will need to get into that.

…although it's possible to rid yourself of the /cygdrive prefix and set
it to just / instead. This comes with a few caveats, but in general
you'd need to ask the Cygwin installation what the prefix is set to via
"mount -p" or you skip the vagaries of the differing prefixes and use
"/proc/cygdrive" instead for scripts that should work either way.
Cygwin can and does process DOS-style paths, but if scripts are involved
that are not prepared to deal with them all bets are off, so they should
be avoided wherever possible.

Yes, that seems likely.

Thank you, Filipp and Eli, for the expertise on this.
