compiling gnupg-1.0.6 on SCO OpenServer 5.0.x

[Scott Powell]

Hello. I am attempting to compile gpg on a SCO OpenServer 5.0.x platform
(have tried it on both 5.0.5 and 5.0.6) and am getting the same results
each time:

1) I run ./configure which completes fine
2) I run make and it bombs with the following:

...
gcc -E -I../include -DHAVE_CONFIG_H -I. -I. -I.. mpih-mul1.S | grep -v
'^#' > _m
pih-mul1.s
gcc -DHAVE_CONFIG_H -I. -I. -I.. -I../include    -g -O2 -Wall  -c
