Thanks for the report. This is also a Debian bug [1], and their patch
is [2].
[1] http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=506684
[2]
http://patch-tracking.debian.net/patch/series/view/guile-1.8/1.8.5+1-4.1/dont-redefine-jmp_buf.diff
I will work on this soon. I expect my fix to be similar to Debian's -
i.e. introducing scm_jmp_buf, scm_setjmp and scm_longjmp - but not
identical.
