The wording for the -i flag in the calc man page
was fixed. help/unexpected, help/rand,
help/random, and help/config were updated. The
${READLINE_EXTRAS} Makefile variables were split
out from ${READLINE_LIB} for Fedora RPM
requirements. When the Makefile variable
${ALLOW_CUSTOM} is not defined or empty, the
libcustcalc library is not built. Bit 8 (0x80) of
calc_debug is reserved for custom debugging. The
length of a FILEPOS copy was fixed. The way the
Makefile can force the calc byte order was
changed.
