build failure and -Werror

[Gerhard Wesp <gwesp at cosy dot sbg dot ac dot at>]

  hi!

  i'm trying to compile gcc-2.95.2 with libstdc++-2.90.8 on a Linux
2.2.14 i586 machine.  all seems to go well, until all of a sudden the
build fails---see below:

  what should i do?  why is the library being compiled with -Werror?  
would it be a solution to just switch it off in the makefile?

  sorry if this question was answered before, i'm only on the list since 
yesterday!  did search the archive, though.

greetings,
-gerhard
