Moreover, our configure machinery expects a version of type x.y.z.p and 
the last digit (possibly missing) is assigned to LYX_RELEASE_PATCH).
See, for example, config/lyxinclude.m4:
...
dnl Extract the single digits from PACKAGE_VERSION and make them available.
dnl Defines LYX_MAJOR_VERSION, LYX_MINOR_VERSION, LYX_RELEASE_LEVEL,
dnl LYX_RELEASE_PATCH (possibly equal to 0), LYX_DIR_VER, and LYX_USERDIR_VER.
AC_DEFUN([LYX_SET_VERSION_INFO],
[lyx_major=`echo $PACKAGE_VERSION | sed -e 's/[[.]].*//'`
  lyx_patch=`echo $PACKAGE_VERSION | sed -e "s/^$lyx_major//" -e 's/^.//'`
  lyx_minor=`echo $lyx_patch | sed -e 's/[[.]].*//'`
  lyx_patch=`echo $lyx_patch | sed -e "s/^$lyx_minor//" -e 's/^.//'`
  lyx_release=`echo $lyx_patch | sed -e 's/[[^0-9]].*//'`
  lyx_patch=`echo $lyx_patch | sed -e "s/^$lyx_release//" -e 's/^[[.]]//' -e 's/[[^0-9]].*//'`
  test "x$lyx_patch" = "x" && lyx_patch=0
  lyx_dir_ver=LYX_DIR_${lyx_major}${lyx_minor}x
  lyx_userdir_ver=LYX_USERDIR_${lyx_major}${lyx_minor}x
  AC_SUBST(LYX_MAJOR_VERSION,$lyx_major)
  AC_SUBST(LYX_MINOR_VERSION,$lyx_minor)
  AC_SUBST(LYX_RELEASE_LEVEL,$lyx_release)
  AC_SUBST(LYX_RELEASE_PATCH,$lyx_patch)
  AC_SUBST(LYX_DIR_VER,"$lyx_dir_ver")
  AC_SUBST(LYX_USERDIR_VER,"$lyx_userdir_ver")
])
...

So, using x.y.z-p, LYX_RELEASE_PATCH will be assigned the value 0 
instead of p.
