When I tried to compile ELM 2.2 PL5 on an Encore Multimax running UMAX V,
the compile failed tue to some #ifdef SV_INTERRUPT's. UMAX V 2.1 includes a
lot of BSD in the kernel, but some things (like sigvec()) aren't available
for the user. Still, some #defines for them are in the include files.
ELM 2.2 uses the #define SV_INTERRUPT as an indication that the sigvec()
call is there, which fails on our system. The following patch correct this
in the following way:
o An extra check is added to Configure to see if the sigvec() call
is defined in /usr/incldue/signal.h. I also changed some defaults
to reflect a system with smart routers and reliable adresses.
o A few lines are added to config.h.SH to #define or #undef a new
constant, SIGVEC, which is used instead of SV_INTERRUPT to see
if sigvec() is available.
o Two #ifdef SV_INTERRUPT's in src/init.c are changed to
#ifdef SIGVEC.
This patch is compiled from three non-context diffs and should be sent to
the patch command by using "patch -p < Patch" in the elm 2.2 source
root directory.
THIS IS AN UNOFFICIAL PATCH that I hope syd@dsi.com will include in a
future official patch.
