taylor 380b0de996 extra safety check when creating a default path string, filename is optional be we need to available if root0 is missing (CFILE not initted yet) 
fix that crazy compiler<->constructor<->linker<->server.txt deal caused by some bad code and a freaky link thing in freespace.cpp

* $Author: taylor $
*
* Functions to keep track of and find files that can exist
* on the harddrive, cd-rom, or in a pack file on either of those.
* This keeps a list of all the files in packfiles or on CD-rom
* and when you need a file you call one function which then searches
* all those locations, inherently enforcing precedence orders.
*
* $Log: not supported by cvs2svn $
* Revision 2.33 2005/12/28 22:06:47 taylor
* fix up cf_find_file_location() and related elements so that it's safer (based on WMC's work, but actually safe this time ;))
*
* Revision 2.32 2005/12/06 03:13:49 taylor
* fix quite a few CFILE issues:
* use #define's for path lengths when possible so it's easier to move between functions
* fix huge Cfile_stack[] issue (how the hell did that get through :v: QA?)
* add Int3() check on cfopen() so it's easier to know if it get's called before cfile is ready to use
* move path separators to pstypes.h
* fix possible string overruns when setting up CFILE roots
* make sure we don't try to init current directory again thinking it's a CD-ROM
* add the list of VP roots to debug log, this will undoubtedly be useful
* when -nosound is use go ahead and set -nomusic too to both checks are correct
* add list of cmdline options to debug log
* fix possible overwrite issues with get_version_string() and remove '(fs2_open)' from string plus change OGL->OpenGL, D3D->Direct3D
*
* Revision 2.31 2005/11/16 21:25:34 taylor
