Hi All,
Compiling vim 8.0.0596 using the new gcc 7.1 (mingw) yields a few new
warnings, like so:
...
gcc -c -Iproto -DWIN32 -DWINVER=0x0603 -D_WIN32_WINNT=0x0603
-DHAVE_PATHDEF -DFEAT_NORMAL -DHAVE_STDINT_H -pipe -march=n
ative -Wall -O3 -fomit-frame-pointer -freg-struct-return -s ex_docmd.c
-o objnative/ex_docmd.o
In file included from ex_docmd.c:14:0:
ex_docmd.c: In function 'eval_vars':
vim.h:1584:23: warning: 'result' may be used uninitialized in this
function [-Wmaybe-uninitialized]

^~~~~~

The attached patch appears to resolve the one about strlen(), but I am
not sure about the others.
Cheers
