The file header-files-osr5-rr.tar.gz contains OpenServer 5.0.7 MP3 system header file modifications that I have made for compatibility with the FSU-threads and GNU Pth user space threads packages as well as some mods to string headers for ease of porting. The contents should be as follows: usr/include/sys/types.h usr/include/strings.h usr/include/synch.h usr/include/string.h usr/include/limits.h usr/include/sys/types.h.00 usr/include/strings.h.00 usr/include/synch.h.00 usr/include/string.h.00 usr/include/limits.h.00 The files with .00 suffix are the originals prior to modification. After installing these modified versions, use -D_PTH_PTHREAD_H_ to compile applications that use FSU-threads or GNU Pth. Use -D_NEED_STRINGS_H to compile applications that think the strcasecmp and strncasecmp functions are declared in /usr/include/string.h These files are provided for reference and are not officially supported by SCO. Use at your own risk. Ron Record rr@sco.com 29-Mar-2005
