- Update to 2.15.0.5:
* make clobber now removes the legacy files: have_fpos.h, help/man,
and help/usage. The latter 2 are now managed as help aliases
in help.c.
* make install now removes the legacy files: ${HELPDIR}/man
and ${HELPDIR}/usage.
* Fixed a problem where, when calc was linked with and uses GNU
readline then for any multi-line copy-and-paste, only the first
line is executed. Thanks to GitHub user @malfisya for reporting
this problem, and thanks to GitHub user @gromit1811 for doing
the research needed to overcome deficiencies in the GNU readline
documentation, and for supplying the work-a-round to allow
multi-line copy-and-paste to work as expected!

- Update to 2.15.0.4:
* Fixed bug that caused calc to fail to compile filepos2z() in file.c
on little endian machines for the Debian apcalc package.
* Removed unused macros from zmath.h:
+ SWAP_B32_IN_HASH(dest, src)
+ SWAP_B16_IN_HASH(dest, src)
+ SWAP_B8_IN_HASH(dest, src)
+ SWAP_B32_IN_FLAG(dest, src)
+ SWAP_B16_IN_FLAG(dest, src)
+ SWAP_B8_IN_FLAG(dest, src)
* When SWAP_HALF_IN_B32(dest, src), SWAP_B32_IN_FULL(dest, src),
SWAP_B16_IN_HALF(dest, src), SWAP_B32_IN_bool(dest, src),
or SWAP_B32_IN_LEN(dest, src), SWAP_HALF_IN_FILEPOS(dest, src)
is an assignment such as:
(*(dest) = *(src))
We now case the dest and src pointers to the proper type before
