It is shown that spectral properties of Sturm-Liouville eigenvalue pro
blems with indefinite weights are related to integral inequalities stu
died by Everitt. A result of Reals on indefinite problems leads to a s
ufficient condition for the validity of such an inequality. A Baire ca
tegory argument is used to show that, in general, the inequality under
consideration does not hold.
