Hi!

While doing automated builds using a _very_ recent host GCC (gcc
(basepoints/gcc-15-2866-g9d5c500c4fa, built at 1723293902) 15.0.0 20240810
(experimental)), I got issues with dlltool.c (for --target=i686-mingw32crt and
-target=i686-cygwin):

(See http://toolchain.lug-owl.de/laminar/jobs/binutils-i686-cygwin/51 or
http://toolchain.lug-owl.de/laminar/jobs/binutils-i686-mingw32crt/51)

Should be easy to fix but dropping the explicit array length and introduce a
strlen() based lenght instead of sizeof.
