Solaris7 X86 - ./configure options for GTK+-1.2.0

[sanitation sprint ca (sanitation)]

I've managed to get the whole 9 yards working - Gnome and E, but only
after using the --disable-shm switch wherever applicable. Even tho it
compiles fine without this, things just die on execution. X server
breaks, etc. Am I missing something obvious in kernel settings (like
shmseg = ???) or is this the only way to get things going?
