	Fix issue "compliation with R_NO_REMAP flag" i.e. use of Rf_error and Rf_warning instead of error / warning.

2020-06-12  Martin Maechler  <maechler@stat.math.ethz.ch>

	* R/biginteger.R (c_bigz): export, to be used, e.g.,
	* R/bigq.R (c_bigq): on  lapply(<big>, Fn) to give a <big[qz]> result, see

2020-03-02  Martin Mächler  <maechler@stat.math.ethz.ch>

	* DESCRIPTION (Version): 0.5-14

2016-01-07
	** Some fix

	**Indexing/Subassignment:
	*** Seg.faults in
	Z <- as.bigz(1:7);     Z[1] <- list(1) # --> seg.fault
	Q <- as.bigq(1:7, 7);  Q[1] <- list(1) # --> seg.fault
	Z <- as.bigz(1:7);     Z[1] <- NULL    # --> seg.fault
	Q <- as.bigq(1:7, 7);  Q[1] <- NULL    # --> seg.fault

	** Not working Arithmetic
	*** qq <- as.bigq(c(0:5, NA, 7:8), 12) # shows NA fine, is.na(qq), too, but numerator( qq ) gives 0 instead of NA !!

	** Miscellaneous
	*** unique() silently gives nonsense !
	*** duplicated()  ditto

	** Matrix stuff
	***  as.matrix(as.bigq(1:4)),  as.matrix(as.bigz(1:4)) now (~ 2012) work
	**** NB: to go "back", now have asNumeric()  {instead of expecting as.matrix() to give numeric}

2013-06-07  Martin Maechler  <maechler@stat.math.ethz.ch>
	big changes related to  "a/b" and "b^(-1)";
	also: now give [NA + warning()} rather than an error when
	there is no inverse, a division to 0, or a modulus mismatch

2013-02-14  Martin Maechler  <maechler@stat.math.ethz.ch>

	* man/modulus.Rd: example, (and FIXME)

	* TODO: as.bigz(integer()) and as.bigq(integer()) now both work and
	give a 0-length object; analogously, the basic functions now work
