Update to 3.01a23:

All:

-	Typo fix in README.compile for the mail address.
	Thanks to Dennis Clarke for the catch!

Libschily:

-	libschily/sleep.c and libschily/usleep.c have been modified to work
	with MinGW.

Cdrecord:

-	The timediff function now in addition prints the time diff in
	hours : minutes : seconds . thausands of a second.

	Thanks to a hint from Donald R Laster Jr from Slackware.

Cdda2wav (Maintained/enhanced by Jörg Schilling, originated by Heiko Eißfeldt \ 
heiko@hexco.de):

-	Cdda2wav no longer includes the new paranoia mode "c2check" in the macro
	"proof". This has been done because of a report from Géraud Meyer \ 
<graud@gmx.com>
	that gives hints that the drive:
	Type: ROM, Vendor 'TSSTcorp' Model 'CDDVDW SH-222AB ' Revision 'SB00' MMC+CDDA
	does not handle hidden tracks when "c2check" is active.

Mkisofs (Maintained/enhanced by Jörg Schilling since 1997, originated by Eric \ 
Youngdale):

-	mkisofs was slightly modified to reduce CPU time requirements.
	It now reads/writes in 64kBytes chunks instead of stdio buffer
	size which is typically 8 kB.

-	Fixed a typo in the mkisofs man page.
	Thanks to a hint from Donald R Laster Jr from Slackware.

-	Mkisofs now in addition prints "-iso-level 3 or more required"
	in case that a large file was skipped because of the current mkisofs settings.

	Thanks to a hint from Donald R Laster Jr from Slackware.

-	A problem in isoinfo has been fixed.
	This problem caused "isoinfo -R -find -ls" to print Jan 1 1970 timestamps
	in case that Rock Ridge was not present.
