[2.63] - problem parsing generated configure or config.status

[Unknown]

Hello.

I have problem w/ newest autoconf-2.63 generated files.
This is how it looks in case of git-1.6.3.3 (recently they moved from
2.61 to 2.63):
configure: creating ./config.status
./config.status: line 666: syntax error near unexpected token `;'
./config.status: line 666: `   { (exit 1); exit 1; }; };;'

line 666:    { (exit 1); exit 1; }; };;

At first moment I though that IF I upgrade the bash
it might help but unfortunely not.
This is reproducable, If I touch any autoconf-2.63 generated
configure, bash dies in one place or another.
Files from autoconf-2.61 works just fine.

I am aware that it might be cygwin specific problem.
For example, under linux (same bash-2.05b) everything works just fine.
I not able to compile autoconf myself for that platform due
to lack of perl support (just miniperl, no perl modules or libs).
But still, I have hope that I found a soul who will want to fix that 
mystery.

Regards,
Borg

PS: I can provide more details if I will be able to.
