Compilation of ghostscript 8.63 fails on SCO OpenServer 6.0.0 until line 103 of jasper/acaux/config.guess is changed from i*86:*:5:[78]*) to i*86:*:5:[678]*)
The line in question seems to be line 1030, rather than line 103. (An actual diff with contexts before and after would have been useful...)
One line suggested change committed as r11180 , plus comments taken from the relevant part of automake 1-11, which seems to have an identical change anyway.
