During vectors to ILS 36 about 5 miles west of MYR at 2;000 FT we received a GPWS oral warning 'Whoop; whoop; pull up; terrain terrain' We were IMC so we performed the escape maneuver and climbed to about 3;500 FT and informed ATC. I checked our altimeters which were correct and there was no terrain in the area that could have triggered the GPWS. We continued the approach and landing.
While being vectored for approach in IMC to MYR at 2;000 FT AGL; a CRJ-200 flight crew responded appropriately to a GPWS terrain warning. The reporter checked their altimeter settings; which were correct; and could find no other apparent cause for the warning.
