cannot compile doc2html.c on current cvs (2016-01-31) on MinGW

Hello

I have tried to build the recent cvs tree using  MinGW.

In compiling doc2html.c, I have met a following error.

gcc  <snip>
../../docs/windows/doc2html.c ../../docs/termdoc.c ../../docs/xref.c version.co

../../docs/windows/doc2html.c: In function 'convert':
../../docs/windows/doc2html.c:171:72: error: 'VERSION_MAJOR' undeclared (first use in this function)
     fprintf(b, "<h1 align=\"center\">gnuplot %s patchlevel %s</h1>\n", VERSION_MAJOR, PATCHLEVEL);
                                                                        ^
../../docs/windows/doc2html.c:171:72: note: each undeclared identifier is reported only once for each function it appears in
../../docs/windows/doc2html.c:171:87: error: 'PATCHLEVEL' undeclared (first use in this function)
     fprintf(b, "<h1 align=\"center\">gnuplot %s patchlevel %s</h1>\n", VERSION_MAJOR, PATCHLEVEL);


For gnuplot 5.0.1, the corresponding line was
fprintf(b, "<h1 align=\"center\">gnuplot %s patchlevel %s</h1>\n",  gnuplot_version, gnuplot_patchlevel);


Perhaps config.mgw should be modified to define VERSION_MAJOR and  PATCHLEVEL values.
Am I right?
