	as recommended by the config name rules


Tue Aug 18 14:31:19 1998  Jonathan Larmour  <[e-mail]>

	* src/stdio/common/setvbuf.cxx (_setvbuf): 
	Rename variable names in assert line, otherwise doesn't build
	with asserts on!

Sun Aug 16 18:15:12 1998  Jonathan Larmour  <[e-mail]>

	* src/stdio/input/vfscanf.cxx (_vfscanf): 
	Fix some bugs, although there are some left to fix still. Unrelated
	to the rest of the checkins, so I will check the partial fix in now.

	* src/clibincl/stream.hxx, src/clibincl/stream.inl,
	  src/stdio/common/stream.cxx:
	Add parameters to constructor to allow more things to be done at
	construction time.

	Now we have "new", remove separate "construct" method

	Add more documentation on constructor

	As requested by code review, where possible, move boolean flags
	into separate packed bitfield structure for space efficiency

	Make readbuf_char be usable all the time rather than when configured
	not to be buffering, as it is also needed for non-buffered mode i.e.
	_IONBF

	* src/stdio/common/fopen.cxx:
	Change to use new method of construction from above, using new

	Use thread-specific data, rather than global. And so change errnos
	to access errno entry specifically

	Make process_mode() check for append mode too

	Reformat for coding standards to have { in same line as "verb"

	* src/stdio/common/setvbuf.cxx:

	Change to cope with different way of dealing with buffering policy
	flags etc. in Cyg_StdioStream

	* src/stdio/common/vsnprintf.cxx, src/stdio/common/vsscanf.cxx,
	  src/support/clibdata.cxx:
	Change construction of streams to use new parameters added above,
	and change to use _IONBF mode for string stdio functions,
	otherwise its a waste of memory. And use _IONBF for stderr as the
	ISO standard tells us to!

	Reformat for coding standards to have { in same line as "verb"

	* src/clibincl/streambuf.hxx, src/clibincl/streambuf.inl:
	Change constructor so that it can be set with default size and
	dynamic buffer (if applicable)

	Fix minor bug in destructor - should only call free when allocated
	dynamically

	Change get_buffer_size to return -1 if the buffer was not allowed
	to be set up

	* src/stdio/common/streambuf.cxx:
	Remove unnecessary stdio.h include and add extra comment to whether
	to free bit in set_buffer()

	* src/stdio/common/freopen.cxx:
	Change @@@ to standard fix me string

	* src/stdio/output/fputc.cxx:
	Remove unnecessary "written" variable

Thu Aug 13 15:37:28 1998  Jonathan Larmour  <[e-mail]>

	* src/stdlib/_exit.cxx: 
	Included use of "fix me" line to ensure this is discussed before
	release

	* include/stdlib.h, src/stdlib/abort.cxx, src/PKGconf.mak:
	Add abort.cxx to implement abort(), albeit naively

Thu Jul 30 18:03:09 1998  Jonathan Larmour  <[e-mail]>

	* src/stdio/common/vsscanf.cxx (_vsscanf),
	  src/stdio/common/vsnprintf.cxx (_vsnprintf): 
	Fix initialiser of pseudo string device table that didn't get updated
	when the table changed (Bad proven, no biscuit).

	* src/clibincl/stream.inl (~Cyg_StdioStream): 
	Move invalidation of magic_validity_word to after unlock_me(),
	otherwise it always fails!

Tue Jul 28 21:29:53 1998  Jonathan Larmour  <[e-mail]>

	* src/clibincl/clibdata.hxx: 
	Shorten over-long lines

Tue Jul 28 20:28:23 1998  Jonathan Larmour  <[e-mail]>

	* src/clibincl/stream.hxx (class Cyg_StdioStream),
	  src/clibincl/stream.inl, src/stdio/common/stream.cxx: 
	Clarify some comments and get the CYGDBG_DEFINE_CHECK_THIS and
	CYG_ASSERTCLASS stuff going

	* src/clibincl/stream.inl:
	Put '{'s on same line as "action" as per coding standards
	Shorten over-long lines

Tue Jul 28 15:31:06 1998  Jonathan Larmour  <[e-mail]>

	* src/clibincl/streambuf.inl, src/stdio/common/streambuf.cxx: 
	Move set_buffer() from streambuf.inl to new file streambuf.cxx

	* src/PKGconf.mak (COMPILE): 
	Build new file streambuf.cxx

	* src/clibincl/streambuf.hxx (class Cyg_StdioStreamBuffer): 
	Add METHODS comment

	* src/stdio/common/stream.cxx: 
	Put '{'s on same line as "action" as per coding standards
	Shorten over-long lines

	* include/stdlib.inl, src/stdio/input/vfscanf.cxx,
	  src/stdio/output/vfnprintf.cxx, src/stdlib/div.cxx,
	  src/stdlib/ldiv.cxx, src/stdlib/qsort.cxx, src/stdlib/strtol.cxx,

	Remove, now that it isn't referred to any more
