i think the change to  $$config =~ s/\\n/\\\n"\\n"/g probably was a mistake
(i`m not good in regexes, though). it seems, that all the quotes and \n`s are
being stripped from that file and so it`s no correct "c-source" anymore, imho.

before:
---snipp---
static __initdata char *config = "#\n"
"# Automatically generated make config: don`t edit\n"
"#\n"
"CONFIG_USERMODE=y\n"
---snipp---

after applying patch.266rc1-1 and running make again, it is:
---snipp---
static __initdata char *config = "#
# Automatically generated make config: don`t edit
#
CONFIG_USERMODE=y
---snipp---

i changed the line in the Makefile back to:
$$config =~ s/\n/\\n"\n"/g
which made things better again.

the error i reported is gone, but now "make linux ARCH=um" fails with:

-> see make.log

which doesn`t seem to be related to that change of the regex before.
since this error looks "skas related" for me, i gave it a further try and
disabled skas support in .config - after that, the compile for that
"TT only"-UML runs fine for a while, but unfortunately it also fails in
the end:

-> see make_tt.log

so still no 2.6.6-rc1 or 2.6.6-rc2 (tried both)

for all interested here:
i`m referring to this "build procedure":
http://marc.theaimsgroup.com/?l=user-mode-linux-devel&m=108255364409540&w=2

ps:
>probably because the PERL code needs to be quoted once more.
err - i have a problem in understanding:
why PERL code ?
the statement is in arch/um/kernel/Makefile - is that being parsed by a perl interpreter
during "make" - or does make just use similar language ?
sorry if this sounds dumb - but i`m no developer and i never wrote a makefile myself.

Please post the arch/um/kernel/config.c file the build produced, which gave
the error. The change to the "QUOTE" line is to be analyzed. The other person
("gboutwel" <gboutwel@praize.com>) having problems had not this one because
he did not reach this step.

I've finally seen what it does:

-QUOTE = 'my $$config=`cat $(TOPDIR)/.config`; $$config =~ s/"/\\"/g ;
$$config =~ s/\n/\\n"\n"/g ; while(<STDIN>) { $$_ =~ s/CONFIG/$$config/;
print $$_ }'
+QUOTE = 'my $$config=`cat $(TOPDIR)/.config`; $$config =~ s/"/\\"/g ;
$$config =~ s/\\n/\\\n"\\n"/g ; while(<STDIN>) { $$_ =~ s/CONFIG/$$config/;
print $$_ }'

the change is from:

$$config =~ s/\n/\\n"\n"/g

to:

$$config =~ s/\\n/\\\n"\\n"/g

probably because the PERL code needs to be quoted once more.
