Yes, here is the error message:

and the output file 
/home/adrian/build/glibc-2.15/localedata/tst-xlocale1.out says the 
following:

"TRANSLIT" and "translit" expected to be the same, result -1

strcasecmp_l ("TRANSLIT", "translit", loc)
"TRANSLIT" and "translit" expected to be the same, result -1

strcasecmp_l ("TRANSLIT", "translit", loc)

strcasecmp_l ("ä", "Ä", loc)


After re-installing my entire Slackware-current system (13.37 32-bit) 
and compiling again with only '-mtune=native -O3', it turns out I get 
the same error in make check. Except if I run `make check` again I no 
longer get that error, but another. Really,I do not understand what 
should I do ..

Do I really need tools compiled statically, like the Linux-HOWTO used to 
say in 2004 ?

Can you please include a line in the INSTALL file that --prefix=/usr 
will still install the library directly in the /lib directory, even with 
install_root=$HOME/usr on the make command line ?

Thank you,
