Yes, it is very standard for autotooled packages to be built in this
way. It's a very common way to build software. I ran into this issue
when porting crosstool-ng so that MSYS can be used as the build
machine, but basically anyone who tries to compile GCC on MSYS or
Cygwin using native Windows GCC will hit this problem unless they use
relative paths or one of the other hacks I mentioned to work around
