LPC845 - ARM Compiler V6 - Declaring and using constants in LP845_startup.s assembly code

I am looking for an example with the Arm V6 compiler, for reading and writing GPREG0 register of the PMU on the LPC845.s?

Specifically, how do you do something like a #define in the assembly code with the ARM V6 compiler?

For the V5 compiler, I can do something like this:

DL_SIG_ADDR     EQU     0x40020004 ; GPREG0 address is 0x40020004 

And then use it in the assembly code like so, where I load the GPREG0 address into R1 and then I can read the contents of this register:

LDR     R1, =DL_SIG_ADDR

But for the V6 compiler, if I use the "EQU" instruction, I get a compiler error as follows:
