As far as i can understand the fpc sources it's in compiler/scanner.pas,
line 359ff:
{ Default enum packing for delphi/tp7 }
if (m_tp7 in current_settings.modeswitches) or
(m_delphi in current_settings.modeswitches) then
current_settings.packenum:=1
else if (m_mac in current_settings.modeswitches) then
{ compatible with Metrowerks Pascal }
current_settings.packenum:=2
else
current_settings.packenum:=4;
So it would be 1 fpr Delphi and TP7 mode, 2 for mac (don't know that)
and 4 for all others.
Did a little test program on that. With {$mode objfpc} result is 4, with
{$mode delphi} result is 1. (And the most important for me: Its the
solution to my problem with UIB - will post the reason as an answer to
that posting!)
program Project1;
{$mode objfpc}
{$H+}
Uses SysUtils;
type
TEnumTestType = (
etOne,
etTwo,
etThree,
etFour,
etFive,
etSix,
etSeven,
etEight,
etNine,
etTen,
etEleven,
etTwelve,
etThirteen,
etForteen
);
var
ET: TEnumTestType;
begin
writeln(IntToStr(SizeOf(ET)));
end.

As far as I could find in the docs it depends on $MODE: for $MODE

4 but I could'nt find the default for $MODE DELPHI.
Where did you read that this depends on $MODE ?
It just says that the default (contrary to Delphi) is 4.
Then the doc is wrong, since sizeof (enum with one element) is 1 in
Delphi
mode.
No problem, if someone would tell me the exact behaviour, I will
change it.
