(Red Hat Linux 7.1 3.0.1-3) and
(hppa1.1-hp-hpux11.00)

the linux configure setup:
Configured with: ../configure --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --enable-shared --enable-threads=posix --disable-checking --host=i386-redhat-linux
>Description:
Creating static libraries  the *errno_location() is not
declared.  This is a problem when loading the shared libraries
into TCL because it wants everything defined :

libddftcl.so: undefined symbol: _Z16__errno_locationv
where libddftcl.so is the shared library
linked by 
g++ -shared *.lo  -Wl,--whole-archive *.al *.a  -Wl,-soname -Wl,libddftcl.so.0 -o .libs/libddftcl.so.0.0.0

>How-To-Repeat:
create shared libraries and try to load them in tcl or 
evaluate if errno_location is defined
>Fix:
define errno_location when building shared libraries
