gcc-3.3 -DHAVE_CONFIG_H -I. -I. -I.. -I.. -I.. -I../libguile-ltdl -g -O2 
-Werror -Wall -Wmissing-prototypes -MT eval.lo -MD -MP -MF .deps/eval.Tpo -c 
eval.c  -fPIC -DPIC -o .libs/eval.lo
eval.c: In function `scm_ceval':
eval.c:1966: warning: dereferencing type-punned pointer will break 
strict-aliasing rules
In file included from eval.c:4591:
eval.c: In function `scm_deval':
eval.c:1966: warning: dereferencing type-punned pointer will break 
strict-aliasing rules

which is complaining about this:

  if (scm_stack_checking_enabled_p
      && SCM_STACK_OVERFLOW_P ((SCM_STACKITEM *) &proc))
    {
