binutils-2.19.51.0.3.20090310
gcc-4.3.3

tested on i386-pc-solaris2.10, sparc-sun-solaris2.10, x86_64-unknown-linux-gnu:

"ar rc" seems to work fine on all platforms.

"ar t" seems to work fine on all platforms (output looks right).

"at tv" reports wrong permissions on i386-pc-solaris2.10 / 
sparc-sun-solaris2.10!

"ar xv" extracts invalid archives with wrong permissions on i386-pc-solaris2.10
/ sparc-sun-solaris2.10!

... could be an endian issue ...

this bug causes issues when compiling programs that create and extract archives
during their compile process (recognized with gcc-4.3.3 and libX11-1.2 -->
impossible to compile with binutils-2.19.51.0.3.20090310 on i386-pc-solaris2.10
/ sparc-sun-solaris2.10).

things seem to be fine with binutils-2.19.50.0.1.20081007,
but fail on 2.19.51.0.1.20090106 and 2.19.51.0.2.20090204.

will attach test directory
