nxpUSBlib with CodeSourcery G++ (or GNU Arm Embedded)?

I'm trying to use the nxpUSBlib with CodeSourcery G++, and have run across stuff that appears to be specific to the CodeRed LPCXpresso compiler.  In particular there is a __DATA(USBRAM_SECTION) macro that part of the CodeRed stuff and looks like it depends on special named RAM sections in a CodeRed created linker script.

Is anyone using this library with CodeSourcery?  Is the __DATA(USBRAM_SECTION) necessary?

Then you can do like this:

#if defined(__GNUC__)&&(!defined(__CODE_RED))
#undef__DATA(x)
#define __DATA(x)// your USB RAM section symbol ex: __attribute__((section("usbram"))) 
#endif

That is correct for USBRAM_SECTION, but the __DATA macro is defined in a file called cr_section_macros.h that only comes with the CodeRed compiler/IDE as far as I can tell.

USBRAM_SECTION is defined in HAL_LPC17xx.h as RAM2 or HAL_LPC... whatever processor you are using.  For LPC17xx, it is the 2nd 32K sram section often refered as AHB ram.  You need to define it in the linker script or change it.
