My way (generated libtool):
  # Transform the output of nm in a proper C declaration
  global_symbol_to_cdecl="sed -n -e 's/^T .* \\(.*\\)\$/extern char
  \\1();/p' -e 's/^[BCDEGRST]* .* \\(.*\\)\$/extern char \\1;/p'"

Your way (generated libtool):
  # Transform the output of nm in a proper C declaration
  global_symbol_to_cdecl="sed -n -e 's/^T .* \\(.*\\)\$/extern char
  \\1();/p' -e 's/^'[BCDEGRST]'* .* \\(.*\\)\$/extern char \\1;/p'"

What's the difference when eval'ed? I don't see it.
