Using NCR-UNIX SVR4 MP-RAS Release 3.02
Patchlevel current at March 1998

uname -a >>> UNIX_SV echnaton 4.0 3.0 3433,3434,3432,3437-R Pentium(TM)-MCA
Compiler >>>>> NCR High Performance C Compiler R3.0c
>Description:
It seems that the latest Version of NCR-Unix SVR$ MP-RAS 3.02 
has the same Problem than Solaris and Unixware 1.0 (see below)


 /* Solaris (probably versions 2.4, 2.5, and 2.5.1 with various levels
  * of tcp patches) has some really weird bugs where if you dup the
  * socket now it breaks things across SIGHUP restarts.  It'll either
  * be unable to bind, or it won't respond.
  */

The Problem has not been seen on previous Versions of MP-RAS 
>How-To-Repeat:
unfortunatly not
>Fix:
a very rudimental fix in http_main.c
May not not be the best solustion but it worked

If compiling under NCR Unix MP-RAS 3.02 
after 

#if defined (UW) && UW < 200
#define WORKAROUND_SOLARIS_BUG
#endif

add the following

#if defined SVR4
#define WORKAROUND_SOLARIS_BUG
#endif
