And quit spreading misinformation. Cygwin strives for backwards
compatibility (older apps linked against newer cygwin1.dll will continue
to work without recompilation of the older app). The error was from the
reverse direction - the OP had a newer g++ trying to link against an older
cygwin1.dll because he had multiple copies in his filesystem.
