FYI

In FPC/trunk the GTK2 gboolean type has been changed from "longbool" to a new type "boolean32".

motivation:

There have been some problems with the GTK2 boolean type for a while.

The longbool type that was used till now had the advantage of being 32-bit and compatible to pascal boolean (and pascal if ... then tests), but had the disadvantage that values unequal to 0 and 1 were legal in it, and could be passed to GTK2.

An attempt to fix this using an enum = (gfalse=0,gtrue=1) failed because it needed too many (100+) patches. The compiler devels then implemented a new boolean type, boolean32. This type, if I understood it right is a normal Boolean but 4 bytes wide.

I tested this today, and everything seemed to work. Lazarus only needed one oneline change that I committed, since it is still compatible with the old (2.4.x) situation.

Please keep an eye open the coming days for new gtk2 related problems that could signal there is a problem.

FPC (2.5.1) can be compiled with noboolean32 to get the old situation back.

on two different PC with german locale and Windows XP LongMonthNames[3] = 'M?rz'
------------------------------------------------------------------------

example:

interface
uses
{$ifdef unix}clocale,{$endif}
    ShowMessage('M?rz  ' + LongMonthNames[3]);

Application.MainForm.Font.Charset = DEFAULT_CHARSET

That problem doesn't exist for Debian-Sid Linux !?

LongMonthNames is RTL, which uses the ansi encoding. If you want to show it using the LCL, convert it to UTF8.

thank you for that tipp:

Solution:
ShowMessage('M?rz  ' + AnsiToUtf8( LongMonthNames[3]));

Solution:
ShowMessage('M?rz  ' + AnsiToUtf8( LongMonthNames[3]));
