Hi,
 
Following :- 
 
     http://www.gnu.org/software/libtool/manual/html_node/Cygwin-to-MinGW-Cross.html
 
I have built bison 3.0.1 with a few source mods and using Cygwin :-
 
    export lt_cv_to_host_file_cmd=func_convert_file_cygwin_to_w32
    export lt_cv_to_tool_file_cmd=func_convert_file_cygwin_to_w32
 
    export PATH="/c/MinGW/bin:${PATH}"
    ../../src/bison-3.0.1/configure --build=i686-pc-mingw32 --host=i686-pc-mingw32
 
On running bison.exe I am getting an error message in a popup:-
 
   The procedure entry point _set_invalid_parameter_handler could not be
   located in the dynamic library C:\MinGW\msys\1.0\bin\bison.exe
 
Am I using the right procedure ?
 
Many thanks in advance,
 
Aaron
