Qdll_filename_encoding symbol missing from emacs.c

I just checked out a new source tree of 21.2 and tried to compile it using Mingw32 (./configure i586-pc-mingw32). I get this error: gcc -c -g -O3 -Wall -Wno-switch -Wpointer-arith -Winline -Wmissing-prototypes -Wshadow -Demacs -I. -DHAVE_CONFIG_H -mno-cygwin -Wno-sign-compare -fno-caller-saves -DWIN32_NATIVE -I/usr/lib/../include/mingw32 emacs.c emacs.c: In function `make_arg_list_1': emacs.c:650: `Qdll_filename_encoding' undeclared (first use in this function) emacs.c:650: (Each undeclared identifier is reported only once emacs.c:650: for each function it appears in.) make[1]: *** [emacs.o] Error 1 make[1]: Leaving directory `/cygdrive/c/xemacs/xemacs-21.2/src' make: *** [src] Error 2 [15:58:53] /xemacs/xemacs-21.2> Grepping through the source directory, I can't find Qdll_filename_encoding anywhere. I temporarily worked around it by adding a definition Lisp_Object Qdll_filename_encoding; before the offending function. ('course, i'm getting other errors in compilation, which will be in the next email). Andrew
