Win7 cygwin Gcc 4.8.3-2 (cygwin) Home Disk C: Data Disk E: C:\cygwin64 is the cygwin root
> ./configure && make && make install When installing from my E: disk (E:\Users\Public\Download\Programs\bison) the new bison is not installed to c:\cygwin64\bin. When installing from my C: disk (C:\Users\Public\Download\Programs) the new bison does install to c:\cygwin64\bin. On my laptop with only one disk (C:\) installation proceeds normally. I don't know if this is a bug or a caution or expected behavior. art
