D.gnu - alignment problem causing strange linker error

In my journey of GDC on the PSP, I have encountered this awful mess when trying to use the function sceGumDrawArray with second argument == anything but a literal constant: psp-gdc -c main.d -fversion=Psp psp-gcc -I. -I/usr/local/pspdev/psp/sdk/include -O2 -G0 -Wall -D_PSP_FW_VERSION=300 -L. -L/usr/local/pspdev/psp/sdk/lib module.o main.o -lgphobos -lpspgum -lpspgu -lm -lpspdebug -lpspdisplay -lpspge -lpspctrl -lpspsdk -lc -lpspnet -lpspnet_inet -lpspnet_apctl -lpspnet_resolver -lpsputility -lpspuser -lpspkernel -o DieCrittersDie.elf main.o: In function `_D4main8drawLineFiikZv': main.d:(.text+0x7e0): undefined reference to `_D6pspsdk5pspgu24__T15GU_VERTEX_SHIFTVi3Z15GU_VERTEX_SHIFTi' main.d:(.text+0x7e0): relocation truncated to fit: R_MIPS_GPREL16 against `_D6pspsdk5pspgu24__T15GU_VERTEX_SHIFTVi3Z15GU_VERTEX_SHIFTi' main.d:(.text+0x7e4): undefined reference to `_D6pspsdk5pspgu27__T18GU_TRANSFORM_SHIFTVi0Z18GU_TRANSFORM_SHIFTi' main.d:(.text+0x7e4): relocation truncated to fit: R_MIPS_GPREL16 against `_D6pspsdk5pspgu27__T18GU_TRANSFORM_SHIFTVi0Z18GU_TRANSFORM_SHIFTi' collect2: ld returned 1 exit status I've tried everything including align(16) in front of constant declarations (which were #define's in the C header). This is the prototype of the function in C: void sceGumDrawArray(int prim, int vtype, int count, const void* indices, const void* vertices); Translated to D: void sceGumDrawArray(int prim, int vtype, int count, void* indices, void* vertices); That second parameter, vtype, has to be a literal constant or that error occurs. Even returning a constant from a function call doesn't work. Local variables don't work either. This is a real problem because writing literal numbers is too obscure and error-prone. I hope this is easily fixable. Thanks.
