Since recent system upgrade which pulled in sdcc 4.3.0, build fails with
following error:
/git/libusrp/firmware/include/fx2regs.h:324: syntax error: token -> '+' ; column 26
It seems newer sdcc doesn't like having sums directly in there. Using
parenthesis around the expression fixes the problem.

SDCC, at least from version 3 onwards, has change the names of special
attributes like "at" or "sfr". They are now all prefixed with double-
underscores.
Upstream fx2lib has made that change in commit 3071389d9a868ed553b84809b399008648536fcf
which can be obtained from
