Description

When compiled with HP aCC 3 or 5 (but not 6), the header <bitset> emits the following warnings:

Comments

[Martin Sebor]

This seems to be a problem only with aCC 3.63 but not with 3.73. Let me see if I can work around it (or silence it using a #pragma diag_suppress if aCC 3 has it) for 4.2.2.
