GMP functions that take doubles choke on non-finite values, avoid that. src/ChangeLog addition: 2015-05-10 Aidan Kehoe <kehoea@parhasard.net> * floatfns.c (double_to_integer): Rename this from float_to_int to fit our newer, bignum-compatible terminology. GMP can signal SIGFPE when asked to turn NaN or infinity into a bignum, and we're not prepared to handle that signal if the OS float library routines don't do that, so check for those values explicitly. * floatfns.c (ceiling_two_float): * floatfns.c (ceiling_one_float): * floatfns.c (floor_two_float): * floatfns.c (floor_one_float): * floatfns.c (round_two_float): * floatfns.c (round_one_float): * floatfns.c (truncate_two_float): * floatfns.c (truncate_one_float): Call double_to_integer() with its new name. * number.c: Don't use the {bignum,ratio,bigfloat}_set_double functions directly here, with GMP they can choke when handed non-finite C doubles, call Ftruncate() and the new float_to_bigfloat() from floatfns.c. Maybe we should extend number-gmp.c with GMP-specific implementations that check for non-finite values. tests/ChangeLog addition: 2015-05-10 Aidan Kehoe <kehoea@parhasard.net> * automated/lisp-tests.el: Backslash a few parentheses in the first column for the sake of fontification. * automated/lisp-tests.el: Check that the rounding functions signal Lisp errors correctly when handed positive and negative infinity and NaN.

### Commentary:

## This file copies a single lisp file into an XEmacs package hierarchy and
## performs the necessary magic so that it will be autoloaded at the next
## dump.

## Parameters:
##	$1 -- Full path to an XEmacsen later than 20.3
##	$2 -- Full path to a lisp package tarball to install
##	$3 -- Full path to a lisp directory in an XEmacs package hierarchy
##	      This directory will be created if it does not exist.
##	      NOTE: the directory name should *not* end in a trailing slash


### Code:

XEMACS="$1"			# Not used at present
LISP_FILE="$2"			# Should be a binary package tarball
DEST_DIR="$3"			# Should be a top level package directory

# Test for valid XEmacs executable and valid input file
if [ ! -f "${LISP_FILE}" -o ! -x "${XEMACS}" ]; then
	exit 1
fi

# Test for destination directory, creating if necessary
test -d "${DEST_DIR}" || mkdir "${DEST_DIR}"
test -d "${DEST_DIR}" || exit 1;

# Very simple minded extraction for the first cut
# We'll get more sophisticated later
cd "${DEST_DIR}"
gunzip -c "${LISP_FILE}" | tar xvf -

# Need to refresh the info/dir file, I don't know how to do that.

exit 0
