gprscomp.c: DMEM_PARTITION_1_SIZE bumped from 1600 to 1700 for gcc These large DMEM partitions are used for T_CCD_Globs structure allocations by the GRLC and GRR entities, and this structure contains a jmp_buf for setjmp/longjmp. Our gcc/newlib version of jmp_buf is bigger than TI's TMS470, and the whole structure is now 1636 bytes instead of 1584.
