Dear Jon:
   Thanks a lot, ~ "gcc -m32 . . " worked!
   However, then, I got,
/usr/bin/ld: skipping incompatible ../../libastro/libastro.a when searching for -lastro /usr/bin/ld: cannot find -lastro

A search via Google for 'libastro.a' told this library being a part of the "XEphem" you mentioned, so the library you have maybe was made as 64-bit... The 'file', 'objdump -p' etc commands would tell what this is...

I don't know anything about "Xephem", so if producing this library was one part of the Xephem build process, then that '-m32' for some reason was not transferred to its compile and then you should check why the library was made as a 64-bit one...

Maybe a :

CC="gcc -m32" ; export CC

would be required in the environment in order to get a 32-bit library....
