libstdc++ fails to bootstrap on Tru64 UNIX as of 20060710:

error: expected ',' or '...' before numeric constant
This happens because tr1/random uses __alpha

class gamma_distribution
{
[...]
explicit
gamma_distribution(const result_type& __alpha = result_type(1))
: _M_alpha(__alpha)
which is predefined as 1 on Tru64 UNIX (and probably other alpha systems).
This was introduced by this patch:
2006-07-06 Paolo Carlini <[EMAIL PROTECTED]>
* include/tr1/random (class gamma_distribution<>): Add.
Environment:
System: OSF1 haydn V4.0 1229 alpha
Machine: alpha
host: alpha-dec-osf4.0f
build: alpha-dec-osf4.0f
target: alpha-dec-osf4.0f
configured with: /vol/gcc/src/gcc/configure --prefix=/vol/gcc
--with-local-prefix=/vol/gcc --disable-nls --host alpha-dec-osf4.0f --build
alpha-dec-osf4.0f --target alpha-dec-osf4.0f
--with-gmp-dir=/vol/gnu/obj/gmp-4.1.3
--with-mpfr-dir=/vol/gnu/obj/gmp-4.1.3/mpfr
--enable-languages=c,c++,fortran,java,objc,ada --disable-libmudflap
How-To-Repeat:
Bootstrap as described above.
