Trouble compiling SMOBs

[Steven Greenberg <greenbes at epinions dot com>]

I'm attempting to link guile with an RDF database and some strange things
are happening.  I use two computers at work, both running Red Hat
6.1.  One one machine everything compiles and runs just fine. 
On the second I can get the stand-along guile interpreter to install and
run just fine, but when I try to compile the (unmodified) SMOB example
I get the following error:
> gcc image-type.o myguile.o `guile-config link` -o myguile
> image-type.o: In function `make_image':
> image-type.o(.text+0xef): undefined reference to `SCM_RETURN_NEWSMOB'
> image-type.o: In function `init_image_type':
> image-type.o(.text+0x28e): undefined reference to `scm_make_smob_type_mfpe'
> collect2: ld returned 1 exit status
> make: *** [myguile] Error 1
The only difference between the machines is the version of gcc.  On
the one that works it's version 2.91.  On the one that doesn't it's
version 2.95.2.  Anybody have an idea what's wrong here?

    Many thanks,
    Steve
