Rel. 4.1 93/3/8 Base-line --- @(#)CHANGE-LOG	4.8 93/11/10 GIE REL
-------------------------------------------------------------------------
93/3/20
	pj_init -- added +k_0 as alternative to +k so as to match documentation.

93/3/21
	Laborde projection added.  Primarily for Madagascar grid.
	Considered BETA at moment until info obtained to give adequate
	documentation.

93/3/26
	Oblique Mercator modified to allow processing of Malasian Grid.
	+no_uoff and +rot_conv options added.

93/3/26
	Corrected text in Interim Report:
	p. 12 - +phi's changed to +lat's
	p. 12 - added updated Oblique Mercator documentation

Unresolved:

Reports of errno 25 persist.  Do not know what platform.  Reviewed
	code and can't see problem.
Unknown platform has problem with pj_errno global and linker storage
	allocation.  Seems similar to SG problem that was over come with 
	-common switch.

Rel. 4.1.1 93/3/26 Base-line
-------------------------------------------------------------------------

93/4/2
	gen_cheby.c - added <stdio.h> header.

93/4/3-4
	gen_cheby.c, projects.h - corrected gen_cheby argument declarations
		related to 'proj' argument and prototype.  Often signalled
		warnings, but still managed to execute OK.
	
	pj_init.c - local function get_init had insufficient storage
		defined for copy of file name and id.  Added id define.
		Strncat replaced with correct strncpy (amazingly did not
		cause problems except of one system).

	Proj now compiles on DOS Microsoft 5.0 C compiler.  MS suffers
		same brain-damage as DEC, so requires local strtod function.

	pj_strerrno prototype added to projects.h

	DOS option in strtod.c for MS C's lack of standard macros in neaders.

Rel. 4.1.2 93/4/4 Base-line
-------------------------------------------------------------------------

93/4/8
	Corrected pj_inv so that errno and pj_errno are reset on entry.

93/4/14
	Added elliptical forms to Azimuthal Equidistant (aeqd).

93/4/15
	Corrected positive error return to negative in PJ_lcc.c .

	Added Indian units conversions to pj_units.

Rel. 4.1.3 93/4/15 Base-line
-------------------------------------------------------------------------

93/5/22
	Extensively revised Chebychev approximation procedures and added
	conversion to power series.

93/6/8
	Changed type of pj_param, plus mods to some other internal procedures.

93/6/13
	Modified pj_factors.  Principle mod was that calling program must
	provide base for structure FACTORS.  Additional mods reflect
	optional analytic input from projection modules (see next entry).

	Modified base of PJ structure for projections to supply analytic
	values of partial derivatives, scale factors and/or convergence
	when formulary available.

	Added -V option for proj so as to provide more complete, verbose
	analysis of projection characteristics at selected geographic or
	cartesian point.

93/6/14
	Pj_errno given its own module and projects.h declares it external.
	To cover ANSI standards related to global variable.  SG linker should
	stop complaining.

93/7/15
	Several additions and a couple of minor corrections to elliptical
	tables.

93/8/4
	PJ_ocea.c error in applying k0.

93/8/19
	Minor general corrections.
	Added nadcon conversion procedures and nad2nad program.
	Projects.h modified to reflect nadcon prototypes and stuctures.
	pj_open_lib extracted from pj_init and made global for use in nad_init.

93/8/25
	Corrected pj_open_lib open for both binary and text modes.  Mostly
	for brain damaged DOS.  Also affected calls in pj_init.c and nad_init.c

	Installs and other scripts updated.

Rel. 4.2 93/8/25 Base-line
-------------------------------------------------------------------------

93/9/13
	Improved bch2bps.c code.  Old code not in error.
	Still problems with DEC native C compiler.

93/9/28
	Modified install script for DEC entry, forcing gcc for compilation.

93/9/29
	Problem with due South forward in geod.  Current version will not
	be fixed as it is to be replaced with Vincente algorithm.

93/9/30
	Two corrections in src/Makefile.

Rel. 4.2.1 93/9/30 Base-line
-------------------------------------------------------------------------

93/10/3
	Geod incorrectly computed some forward values when geodesic on the
	merdian.

93/11/2
	Projection stere fails for polar cases because of 0 lat_ts.  Fixed
	by testing for lat_ts specification and setting to 90 degrees when
	lat_ts not specified.  UPS not affected.

93/11/5
	Inverse polar stereographic also failed on 0 x xor y.  Corrected.

93/11/10
	Changed "install" to include "plain" system type for systems that
	do not require special consideration.
