2.8.5 Compile error under Cygwin

[Steve Holden]

I've been struggling to get wxWidgets compiled in order to be able to 
build wxPython; I would get a compile error as follows:

$ ../configure     --prefix=/home/wx28/     --disable-stl 
--disable-unicode --enable-optimise     --enable-debug_flag 
--disable-sound --disable-precomp-headers

everything proceeds along fine until make tries to compile helpdata.cpp, 
when I see

/c/Steve/Projects/wxWidgets-2.8.5/bld-cygwin/bk-deps g++ -c -o 
htmldll_helpdata.o  -D__WXMSW__     -I../src/tiff -I../src/jpeg 
-I../src/png     -DWXUSINGDLL -DWXMAKINGDLL_HTML  -D_FILE_OFFSET_BITS=64 
-D_LARGE_FILES -D__WXDEBUG__ 
-I/c/Steve/Projects/wxWidgets-2.8.5/bld-cygwin/lib/wx/include/msw-ansi-debug-2.8

-fno-strict-aliasing ../src/html/helpdata.cpp
In file included from ../include/wx/busyinfo.h:17,
                  from ../src/html/helpdata.cpp:31:
../include/wx/generic/busyinfo.h:28: error: `wxWindow' has not been declared
../include/wx/generic/busyinfo.h:28: error: ISO C++ forbids declaration 
of `parent' with no type
make: *** [htmldll_helpdata.o] Error 1

Now I am not a C++ programmer, and so I am stabbing around somewhat 
randomly. I have found that the following patch will fix the problem and 
allow me to complete the build:

$ diff -u helpdata.cpp.orig helpdata.cpp
--- helpdata.cpp.orig   2007-09-25 21:41:12.780412800 -0400
+++ helpdata.cpp        2007-09-25 21:42:19.876892800 -0400

  #if wxUSE_HTML && wxUSE_STREAMS

  #ifndef WXPRECOMP
+    #include "wx/window.h"
      #include "wx/intl.h"
      #include "wx/log.h"
  #endif

Not being a wxWidgets regular I don't really feel confident in putting 
this forward as a serious patch (since I can't understand how an 
apparently basic error like this could get by so many pairs of eyeballs. 
So I am assuming that my ignorance stops me from seeing the real problem.

If any reader can explain the issue to me I'd appreciate knowing what 
the real fix should be.

regards
