1.50  Tue Apr  9 12:02:34 PDT 2013
	changed Makefile.PL to check for config.h when building for XS
	with 'gcc', try building with 'cc', and check again.
	If config.h is not found, force Pure Perl mode.

	correct incorrect format for IPv6 embedded IPv4 addresses
	in InetBase v0.8

1.45  Fri Nov 11 13:20:32 PST 2011
	break out the code in InetBase v0.05 that expands short IPv4 
	addresses into dotquad format to account for broken BSD 
	implementations of inet_aton and gethostbyname that do 
	not recognize the short format. EXPORT this as sub 'fillIPv4'
 
	in Util.pm, add 'fillIPv4' to calls to gethostbyname to 
	work around broken inet_aton and gethostbyname implementations
	in certain BSD implementations

	add inet_pton, inet_ntop, AF_INET, AF_INET6

	split the following into NetAddr::IP::InetBase v0.01
	to provide better long term support for IPv6

        inet_ntoa
        ipv6_aton
        ipv6_n2x
        ipv6_n2d

        inet_ntop
        inet_pton
        packzeros
        isIPv4
        isNewIPv4

	thanks to mishikal@yahoo.com for spotting the bug and to
	Mark Martinec mark.martinec+ama...@ijs.si for the solution.
 
1.35  Tue Nov 16 16:28:37 PST 2010
	naip_gethostbyname modified to return undef instead of 
	0 (zero) on failure
 
	thanks to Terry Cassidy enaudishaylee@tc17.com for the bug report
 
	move sub's ipv6_n2d and ipv6_n2x to non-autosplit portion
	of module to eliminate warnings during autosplit of "our" variables

	In Util.xs, 
	changed netswap() to postincrement 
        *a++ = to *a and added increment after save to mollify some
        picky compilers that return possible undefined behavior.
 
        changed type of _128x10 to 'void'
 
1.31  Tue Jun  9 10:31:11 PDT 2009
	ferret out shell value for Makefile.PL when calling

	due to bug in Archive::Tar
 
1.30  Sat Mar  7 16:35:33 PST 2009

	revised UtilPP v1.7 to work around perl 5.8.4 
	failures with certain @_ operations of goto &sub...
	see perl bug [ 23429]. Unfortunately, perl-5.8.4 is
	the distribution of choice for many solaris boxes
 
1.26  Fri Nov 28 23:19:01 PST 2008
	revised XS code to be full re-entrant... thread safe.

	libraries against the perl build for consistency
 
1.23  Sun Nov  2 10:10:38 PST 2008

0.16  Sun Jun 25 16:13:00 PDT 2006

	for spotting those bugs
 
0.15  Tue Jun 13 14:42:34 PDT 2006
	UtilPP.pm v0.07 & Util.xs 'shiftleft' so that the original
	argument is returned when the shift count is '0' or missing
 
0.14  Tue Jun  6 08:37:01 PDT 2006
	add logic to check LIBS => [-lfiles]
	individually. ExtUtils::xxx does a bad job and
	leaves libs that do not exist in the list
	which causes 'siteconf' to blow up on missing libs
	on perl 5.053 (and probably others)
 
0.13  Tue Jun  6 08:33:11 PDT 2006
	added to xs file, 'hopefully' to allow build on windoze platforms

	#if MACRO1 == MACRO2
 
0.10  Sat Jun  3 19:07:51 PDT 2006
	add site configuration to supply u_intxx_t vars
	for Sun OS and others that don't have them
 
0.09  Sun May  7 18:06:43 PDT 2006

	add Util_IS.pm to guarantee that the XS lib is not
	loaded if a previous incarnation of the same version
	has previously been installed on the system and the
	module is built with -noxs

	update minisocket to perl-5.9.3, add header
	file for backwards compatibility

	added test for illegal characters to ipv6_aton
 
	added UtilPP for Pure Perl functionality for the
	WinTel folks that don't have gcc on their systems
 
0.01  Tue Mar 28 16:42:44 PST 2006
	initial release
