The -fno-builtin option does not affect functions that begin with
__builtin. See the GCC manual:
`-fno-builtin'
`-fno-builtin-FUNCTION'
Don't recognize built-in functions that do not begin with
`__builtin_' as prefix. [...]
The problem is probably that the compiler in use, according to
config.log, is GCC 3.4.x, but only GCC 4.x has __builtin_isnan
and __builtin_isinf (although they are not documented). However,
gnulib only uses __builtin_isnan on GCC 4 and later, and PSPP
(including gnulib) does not include any reference to
__builtin_isinf at all.
This makes me suspect that the system in question has broken
system header files. Jason, would you mind grepping through the
system headers in /usr/include (and anywhere else that gets
searched by GCC by default) for references to these
__builtin_is<XXX> functions?
