egcs-19981109 hpux10.20 build failure in libf2c

[tprince at cat dot e-mail dot com]

The following failure occurs when attempting to compile
libf2c/libU77/lbitbits.c while building with make or
make-bootstrap.  Reducing the optimization to -Os does not
affect this, but it compiles successfully at -O.
