Hi, I'm having a frustrating time installing gcc under cygwin. I am taking the very simplest approach: configure and make with no options, using the bash shell. However it stops with an error well into the build. I get different errors with the source code from svn or tarball, the error from the last build is below. As far as I can make out, all the prerequisites for gcc are included in cygwin. Can anyone confirm this? Any other clues? Thanks, Ben ...
