2005-03-29  Robert Dewar  <dewar@adacore.com>

	* errutil.adb, errout.adb:
	Minor comment updates on Line_Terminator references

	* par-ch10.adb: Add ??? comment about line terminator

	* styleg.adb (Check_Line_Terminator): Add check for new switch -gnatyd
	(check dos line terminator).
	(Check_Line_Max_Length): New procedure, split off from the existing
	Check_Line_Terminator routine. Separating this out allows -gnatyf to
	be properly recognized.

	* styleg.adb: Add ??? comment for line terminator reference

	* scng.adb (Check_End_Of_Line): Fix bug of -gnatyf being ignored
	(Check_End_Of_Line): Add -gnatyd handling (check dos line terminators)

	* styleg.ads (Check_Line_Terminator): Add check for new switch -gnatyd
	(check dos line terminator).
	(Check_Line_Max_Length): New procedure, split off from the existing
	Check_Line_Terminator routine. Separating this out allows -gnatyf to
	be properly recognized.

	* stylesw.ads, stylesw.adb:
	Add handling for new -gnatyd switch (check dos line terminator)

	* switch-c.adb: Recognize new -gnatyd switch (check dos line terminator)
	Recognize -gnatwb/-gnatwB switches
	Include Warn_On_Bad_Fixed_Value for -gnatg

	* usage.adb:
	Add line for new -gnatyd switch (check dos line terminator)

	* usage.adb: Add lines for -gnatwb/-gnatwB

	* vms_data.ads: Add entry for NOCRLF (-gnatyd)

	* vms_data.ads: [NO_]BAD_FIXED_VALUES synonym for -gnatwb/-gnatwB

	* gnat_ugn.texi: Fix overlong lines
	Document new -gnatyd switch
	Document new -gnatwb/-gnatwB switches

+@cindex Small value
+This switch activates warnings for static fixed-point expressions whose

+dependent, since an implementation is free to choose either of the multiples

+required behavior, and it is better to specify a value that is an exact
+multiple, ensuring predictable execution. The default is that such warnings
