What is the 'as' the compiler is : looking for? `as' is the assembler. GPC is meant to be part of an existing cygwin32 toolchain, which you don't have. You can get the remaining b17.1 parts as: ftp://agnes.dida.physik.uni-essen.de/home/janjaap/cygwin32/devtools.i486-cygwin32-b17.1.zip Or, you can get a b18 toolchain (GPC + required tools) as: ftp://agnes.dida.physik.uni-essen.de/home/janjaap/cygwin32/gpc-970624.i386-cygwin32-b18.zip Don't mix up b17.1 and b18 binaries -- it won't work.
