Thanks, Brian - for the moment, my interest is in having gsl build 
successfully with mingw64 in the MSYS shell.

It's probably not apparent in the post I sent but, in the actual output to 
the console, there's no space between ".libs/libgsl.lax/libgslblock.a" and 
"//c/_64/comp/gsl-1.14/block/.libs/libgslblock.a" in the error message - 
which strikes me as odd. And why are there *two* adjacent forward slashes in 
there ?

It's also odd that the preceding 'cd .libs/libgsl.lax/libgslblock.a && ar x 
"/c/_64/comp/gsl-1.14/block/.libs/libgslblock.a"' command has succeeded - 
and I can manually cd to .libs/libgsl.lax/libgslblock.a and run 'ar x 
"/c/_64/comp/gsl-1.14/block/.libs/libgslblock.a"' without any problems (and 
no warnings being emitted).

If there's no further response here by tomorrow morning I'll see if the guys 
on the mingw64 mailing list have any ideas as to what's going wrong. So 
near, and yet so far ...
