Neither Cygwin nor msys are compilers or toolchains.  Nor is MSVS, for
that matter.  That would only be a problem if you misunderstood what
they are.

Drive letters on Windows have always been a PITA.  Usually, IME, it is
not a big issue for compilation - most of your include directories will
be on the same drive you are working in (with "system" includes already
handled by the compiler configuration).  Use a makefile, make the base
part a variable, then at most you only have to change one part.  It's a
good idea anyway to have things like base paths to includes as a
variable in the makefile.

One of the differences between msys and cygwin is the way they handle
paths - msys has a method that is simpler and closer to Windows, while
cygwin is a bit more "alien" but supports more POSIX features (like
links).  In practice, with programs compiled for the "mingw" targets you
can usually use Windows names and paths without further ado.  On my
Windows systems, I put msys2's "/usr/bin" directory on my normal PATH,
and from the standard Windows command prompt I happily use make, grep,
less, cp, ssh, and other *nix tools without problems or special
consideration.
