Subject: Bug: Incorrect type in ob-C.el for D code [8.3.4 (8.3.4-elpa @ ~/.emacs.d/elpa/org-20160222/)]

Issue is fairly straightforward. When evaluating a D code block that
includes a table var, this error is thrown by the DMD compiler.
~\Temp\babel-1032v-N\C-src-1032Xig.d(25): Error: cannot implicitly convert
expression (row) of type ulong to uint
Failed: ["dmd", "-v", "-o-", "~/Temp/babel-1032v-N/C-src-1032Xig.d",
"-I~/Local/Temp/babel-1032v-N"]
The type `ulong` is not appropriate for the generated code, as it
represents an array index. The fix is to change line 434 in ob-C.el from:
"string %s_h (ulong row, string col) { return
%s[row][get_column_num(%s_header,col)]; }"
to read:
"string %s_h (size_t row, string col) { return
%s[row][get_column_num(%s_header,col)]; }"
The use of `size_t` is correct for array indexes, and fixes the error in
the compiler.
Reference: http://dlang.org/spec/portability.html
"Array indices should be of type size_t."
System information follows.
Thank you!
