23 * from LoCosto version of this file, as it is used by l1_cmplx.c
24 * fairly extensively.

26 * Disassembly-matching reconstruction has revealed that the constant
27 * in question was originally 210 in the TCS211 version, and then
28 * increased to 220 in the LoCosto source. We currently seek to match
29 * TCS211 without any changes, hence we are setting it back to 210.
