Below is a message I posted earlier today, on the MinGW-users list at SourceForge.
The topic relates to getting autoconf generated configure scripts to provide an appropriate default ${prefix} value, for native Win32 builds of autoconf managed packages, when using MSYS/MinGW as the build environment.
Dealing with Windows paths from the unixish environment is a real problem. For my package, I use a home-brewed shell script which obtains the actual Windows path based on the Cygwin/MinGW mount and applies the desired amount of backslash escaping to survive any remaining configure script processing.
The problem is not specific to the installation prefix.
I have attached the script for reference.
