+Subject: [PATCH] Ensure that msgfmt doesn't encounter problems during gcc
+ bootstrapping.
+
+Solves error messages like the following:
+
+msgfmt: /var/tmp/portage/sys-devel/gcc-4.1.2/work/build/./gcc/libgcc_s.so.1: version `GCC_4.2.0' not found (required by /usr/lib/gcc/x86_64-pc-linux-gnu/4.5.3/libstdc++.so.6)
+
+The libgcc_s.so used during build doesn't satisfy the needs of the
+libstdc++.so that msgfmt is linked against. On the other hand, msgfmt
+is used as a stand-alone application here, and what library it uses
+behind the scenes is of no concern to the gcc build process.
+Therefore, simply invoking it "as usual", i.e. without any special
+library path, will make it work as expected here.

+Subject: [PATCH] Alpine musl package provides libssp_nonshared.a. We link to
+ it unconditionally, as otherwise we get link failures if some objects are
+ -fstack-protector built and final link happens with -fno-stack-protector.
+ This seems to be the common case when bootstrapping gcc, the piepatches do
+ not seem to fully fix the crosstoolchain and bootstrap sequence wrt.
+ stack-protector flag usage.

+Subject: [PATCH] Use generic errstr.go implementation on musl
+
+glibc provides two version of strerror_r() depending on a feature test
+macro. The first is the XSI-compliant version which returns an int, the
+second is GNU-specific and returns a char pointer.
+
+Similarity, gcc's libgo provides two implementations of Errstr() both of
+which use strerror_r(). On Linux, it is assumed that the GNU-specific
+strerror_r version is used. However, musl only provides the
+XSI-compliant version of strerror_r. This patch enables the generic
+Errstr() implementation which also uses the XSI-compliant version of
+strerror_r.

+.Sh NAME
+.Nm getent
+.Nd get entries from administrative databases
+.Sh SYNOPSIS
+.Nm getent
+.Ar database
+.Op Ar key ...
+.Nm getcap
+.Ar database
+.Op Ar key ...
+.Sh DESCRIPTION
+The
+.Nm
+program retrieves and displays entries from the administrative
+database specified by
+.Ar database ,
+using the lookup order specified in
+.Xr nsswitch.conf 5 .
+The display format for a given
+.Ar database
+is as per the
+.Dq traditional
+file format for that database.
+.Pp
+.Ar database
+may be one of:
+.Bl -column "protocols" "user:passwd:uid:gid:gecos:home_dir:shell" -offset indent -compact
+.It Sy Database Ta Sy Display format
+.It disktab Ta entry
+.It ethers Ta address name
+.It gettytab Ta entry
+.It group Ta group:passwd:gid:[member[,member]...]
+.It hosts Ta address name [alias ...]
+.It netgroup Ta (host,user,domain) [...]
+.It networks Ta name network [alias ...]
+.It passwd Ta user:passwd:uid:gid:gecos:home_dir:shell
+.It printcap Ta entry
+.It protocols Ta name protocol [alias ...]
+.It rpc Ta name number [alias ...]
+.It services Ta name port/protocol [alias ...]
+.It shells Ta /path/to/shell
+.El
+.Pp
+If one or more
+.Ar key
+arguments are provided, they will be looked up in
+.Ar database
+using the appropriate function.
+For example,
+.Sy passwd
+supports a numeric UID or user name;
+.Sy hosts
+supports an IPv4 address, IPv6 address, or host name;
+and
+.Sy services
+supports a service name, service name/protocol name, numeric port, or
+numeric port/protocol name.
+.Pp
+If no
+.Ar key
+is provided and
+.Ar database
+supports enumeration, all entries for
+.Ar database
+will be retrieved using the appropriate enumeration function and printed.
+.Pp
+For
+.Xr cgetcap 3
+style databases
+.Sy ( disktab ,
+.Sy printcap )
+specifying a key, lists the entry for that key, and specifying more arguments
+after the key are used as fields in that key, and only the values of the keys
+are returned.
+For boolean keys
+.Dv true
+is returned if the key is found.
+If a key is not found, then
+.Dv false
+is always
+returned.
+.Sh DIAGNOSTICS
+.Nm
+exits 0 on success,
+1 if there was an error in the command syntax,
+2 if one of the specified key names was not found in
+.Ar database ,
+or 3 if there is no support for enumeration on
+.Ar database .
+.Sh SEE ALSO
+.Xr cgetcap 3 ,
+.Xr disktab 5 ,
+.Xr ethers 5 ,
+.Xr gettytab 5 ,
+.Xr group 5 ,
+.Xr hosts 5 ,
+.Xr networks 5 ,
+.Xr nsswitch.conf 5 ,
+.Xr passwd 5 ,
+.Xr printcap 5 ,
+.Xr protocols 5 ,
+.Xr rpc 5 ,
+.Xr services 5 ,
+.Xr shells 5
+.Sh HISTORY
+A
+.Nm
+command appeared in
+.Nx 3.0 .
+It was based on the command of the same name in
+.Tn Solaris
+and
+.Tn Linux .
