Confirmed here. It seems related to the change to autoconf 2.5x,
but it is not working as intended. The configure code has
if test "${r_cv_prog_f77_append_underscore}" = yes \
|| test -n "${F2C}"; then
dgemm_func=dgemm_
else
dgemm_func=dgemm
fi
...
AC_CHECK_LIB(f77blas, $dgemm_func,
BLAS_LIBS="-lf77blas $BLAS_LIBS", , $BLAS_LIBS $FLIBS)
and r_cv_prog_f77_append_underscore is being set correctly, but only later
in the configure. I think that comes from following the autoconf
recommended order of tests (libraries, headers, ...), but we need an
exception here.
