* Revisions :
* $Log: loaders.c,v $
+ * Revision 1.31 2001/10/26 17:39:01 oes
+ * Removed csp->referrer
+ * Moved ijb_isspace and ijb_tolower to project.h
+ *
+ * Revision 1.30 2001/10/25 03:40:48 david__schmidt
+ * Change in porting tactics: OS/2's EMX porting layer doesn't allow multiple
+ * threads to call select() simultaneously. So, it's time to do a real, live,
+ * native OS/2 port. See defines for __EMX__ (the porting layer) vs. __OS2__
+ * (native). Both versions will work, but using __OS2__ offers multi-threading.
+ *
+ * Revision 1.29 2001/10/23 21:38:53 jongfoster
+ * Adding error-checking to create_url_spec()
+ *
+ * Revision 1.28 2001/10/07 15:40:39 oes
+ * Replaced 6 boolean members of csp with one bitmap (csp->flags)
+ *
+ * Revision 1.27 2001/09/22 16:36:59 jongfoster
+ * Removing unused parameter fs from read_config_line()
+ *
+ * Revision 1.26 2001/09/22 14:05:22 jongfoster
+ * Bugfix: Multiple escaped "#" characters in a configuration
+ * file are now permitted.
+ * Also removing 3 unused headers.
+ *
* Revision 1.25 2001/09/13 22:44:03 jongfoster
