annotate libinterp/dldfcn/__ode15__.cc @ 27108:2e5d8cdc7087
eliminate remaining uses of BEGIN_INTERRUPT_WITH_EXCEPTIONS macro
All uses of the BEGIN_INTERRUPT_WITH_EXCEPTIONS and
END_INTERRUPT_WITH_EXCEPTIONS should have been removed in Octave at
the same time that they were defined to { and }, respectively, but
some were missed.
Files affected: __ode15__.cc, ov-java.cc, DASPK.cc, DASRT.cc,
DASSL.cc, LSODE.cc, and Quad.cc.
