unknown Opcode '.pword'

Question

When I compile my code I am getting a unknown Opcode '.pword' error. The only line of code in my project that has .pword is:

do {
    __asm__ volatile (" .pword 0xDA4000");
    Nop();
} while(0)

Commenting the line out does nothing.

I searched .pword 0xDA4000 and know it is supported by the IDE MPLab for PICs.

In my case the IDE I am using is CrossStudio for a STMf32f2xx chip.

I have the updated CrossStudio which comes with binutils 2.21 and gcc 4.6.0

I initially had a problem with compiling unnamed structs and unions but adding -fms-extensions into additional C compiler options fixed it.

I dont know if I need to do something similar to fix Opcode '.pword' error.

could it just be that .pword is only a PIC opcode?

In MPLAB ASM30 assembler the .pword declare 24 bit constant in code memory. It can be also any MPLAB ASM30 instruction.
