Hi Reid,<br>
<br>
Thanks for the explanation. The hack didn't seem to work...<br>
<br>

<div>Basically the clang-cl driver does not accept the same set
of command line flags that the gcc-style driver accepts
because there are conflicts around some commonly used options
(-MD, for example). We make gcc-style flags available in
clang-cl on an as-needed basis assuming there are no
conflicts. Understandably, it is really confusing to users to
have to understand two sets of flags and it might be worth
revisiting that decision.</div>
<div><br>
</div>
<div>The -Xclang flag is a workaround that bypasses both the
gcc-style and cl-style flags processing and directly accesses
the clang -cc1 command line flag set, which is yet again
different from either of the first two.</div>

some C++ source files that mix in small bits of Obj-C. On
the Mac, these files are marked to be compiled as Obj-C++.
Looking at the clang help, it seems that the option for that
is "-ObjC++". However, when I add that in Additional Options
I get an error message:<br>
<br>
CL> : error : invalid integral value 'bjC++' in '-ObjC++'<br>
<br>
I see this same message if I put "-Xclang" in front of
"-ObjC++".<br>
<br>
Is there a way to get the code to compile as Obj-C++ on
Windows?<br>
