...finally available at http://www.magma.ca/~wjr/. Besides the name change, this long overdue update provides a more complete and reliable header file translation for Windows XP (adjust INI file for Windows Vista), including drag-and-drop support for multiple H file translation (see ReadMe - room for improvement, for now, please pay attention when confirming the destination folder!).
I shall add though that I am aware of most of the remaining output imperfections... so, on that note, editing not included, some assembly required - mostly removal of #include lines for files referred to more than once (GoAsm provides a warning).
#if the thought of playing with header files makes your head spin, another alternative is the GoAsm Header Project over at http://www.quickersoft.com/donkey/index.html.
