The strange thing is that the error vanished yesterday on my work PC,
but using the same tools I still get it on my home PC:

Starting program: C:\Users\deyke\emacs-build\work\lisp/../bin/my-emacs.exe -batc
h --no-init-file --no-site-file --multibyte -f batch-byte-compile url/vc-dav.el

Breakpoint 3, get_doc_string (filepos=-2581128, unibyte=0, definition=0)
    at doc.c:196
196             error ("Cannot open doc string file \"%s\"", name);
(gdb) up 1

(gdb) print function
$1 = 27819993
(gdb) xtype
(gdb) xsymbol
$2 = (struct Lisp_Symbol *) 0x1a87fd8

As for your last question, I'm not using MSYS. My setup includes:

english XP Pro SP2
current cygwin
MinGW-3.1.0-1 in PATH before cygwin

If I start the emacs which was built during bootstrap it reports:
