Description

Verilator version: Verilator 3.812 2011/04/06 rev verilator_3_811-18-ga20b4f2
When a module with a DPI-C exported task is verilated and compiled, gcc complains that 

ISO C++ forbids declaration of 'svBitVecVal' with no type
when it compiles the file V<base>__ALLcls.cpp. This seems to be due to the fact that svdpi.h is not included.
