Can you try out the following GDB script:
b main
run -q -c 0
b get_thread_stack_base
c
b scm_get_stack_base
c
finish
finish
quit
Save it to a file, say `the-script', `cd' to the top build directory and
run:
./libtool --mode=execute gdb ./libguile/guile -x the-script
Then you can post the GDB output here.
The goal is to understand which part of the code is used to determine
the stack base, and what it returns.

OK, they are truly declared as ints, which truly breaks strict aliasing
rules. Then we should either compile that file with
`-fno-strict-aliasing' or not use `-Werror'.

I am roughly assuming OSF == Tru64 (aka. OSF/1). I don't see "OSF"
listed in the above page. According to
http://en.wikipedia.org/wiki/Open_Software_Foundation, OSF is was merged
with the Open Group.
Anyway, do you have pointers to documentation or standards that describe
`DQNAN' and `DINFINITY'? I don't see anything like this at
opengroup.org.

Is that under /usr/include or /usr/include/sys?
Thank you!
