FYI, the last time I tried to build the 2.95 toolchain under Cygwin (back in 2009), it wasn't possible. The version of GCC that was included in a Cygwin install in 2009 was too new to compile gcc 2.95. After some trial and error, I concluded that 3.2 was the oldest GCC version that could be built using the gcc included in Cygwin in 2009. Perhpas the gcc that's included in Cygwin now can build gcc versions older than 3.2, but I'd be surprised... -- Grant Edwards grant.b.edwards Yow!
