* In Perl_yylex(), no need to Newxz() a buffer we immediately write to.Nicholas Clark2009-05-191-1/+1

* Amelioration of the error message "Unrecognized character %s in column %d"Claes Jakobsson2009-05-141-2/+14
| | | | | | Changes the error message to "Unrecognized character %s; marked by <-- HERE after %s<-- HERE near column %d". This should make it a little simpler to spot and correct the suspicious character.
* Remove all #ifdef MACOS_TRADITIONAL code in core and non-dual-life XS code.Nicholas Clark2009-04-271-10/+0
| | | | | | | | (MacOS support was removed from MakeMaker in 6.22, and merged to blead on 15th December 2004 with 5dca256ec738057dc331fb644a93eca44ad5fa14. After this point MacOS wouldn't even have been able to build the perl binary, because it would not have been able to build DynaLoader. If anyone wishes to resurrect MacOS, start by reversing this commit and the relevant part of that commit.)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Attached is a patch for this problem. The root cause was that S_scan_const() was not recoding to utf8 under some circumstances when it should be. I also changed it so that in all places, the flag that indicates the output is in utf8 is changed from false to true if and only if the destination is recoded to utf8. One place was skipping this, and then setting it unconditionally later on. In one place in the routine, the routine had code to do the recoding itself. In the other places, it called sv_utf8_upgrade(). I changed it to call the subroutine in all cases. I fixed a bug that would appear only on EBCDIC machines where constants of the form \N{U+....} would have been interpreted as EBCDIC. And in inspecting the code, I realized there were problems with growing the scalar value to fit the input. I cleaned those up. I also added a number of comments to document things I found out, and changed some existing ones to be more accurate. Since no one responded to my request for where to put the test cases, and I couldn't figure out a good place to put them, I added a new test file, t/uni/lex_utf8.t.
