So I am trying to configure and install mutt, and the first error I see is
at the end of configure:

configure: creating ./config.status
chmod: changing permissions of './config.status': Permission denied
configure: error: write failure creating ./config.status

Well, looks like its right:

[~/src/mutt]> chmod +x config.status
chmod: changing permissions of ‘config.status’: Permission denied

[~/src/mutt]> uname -a
CYGWIN_NT-6.3 ux31a 2.0.0(0.287/5/3) 2015-04-15 17:39 x86_64 Cygwin

[~/src/mutt]> getfacl .
# file: .
# owner: ismail
# group: ismail
user::rwx
group::r-x
group:SYSTEM:rwx
group:Administrators:rwx
mask:r-x
other:r-x
default:user::rwx
default:group::r-x
default:group:SYSTEM:rwx
default:group:Administrators:rwx
default:mask:r-x
default:other:r-x

[~/src/mutt]> getfacl config.status
# file: config.status
# owner: ismail
# group: ismail
user::rwx
group::r-x
group:SYSTEM:rwx
group:Administrators:rwx
mask:r-x
other:r-x

Any ideas? :)

Thank you.
