IMHO, -frounding-math should be the default, unless -ffast-math is given.

This problem is fixed by specifying the -frounding-math command line option,
which informs the compiler that non-default rounding modes may be used.
With gcc-3.4, specifying this command line option disables this

Even without fenv.h, the function could be in a library called in a directed
rounding mode.
And one can change the rounding mode via a standard function in the glibc, no
need for a pragma.

Note GCC does not know about the rounding mode, in fact the round mode is only
changeable in C99
by the #pragma which GCC does not do right now and I thought that is a
different PR already.
