[Rd] Win 64 package build - ERROR: loading failed for 'x64'

[John Nolan]

I did use the name Makevars.win, sorry for mistyping the name in my message as Makevar.win.

I changed the extension on the library names from *.lib to *.a in the output below precisely to avoid complaints from this list; sorry for the confusion caused by missing 2 occurrences.

The 64 bit library works fine: I can compile, link, and run a stand-alone test program that uses the 64 bit library test_win64.a.  Since that works fine, I suspect the problem is somewhere in the process where R builds and links the 64 bit DLL.  It may be a configuration problem, but if so, I don't understand why it does not show up in the rcmd build stage?

1) Use Makevars.win, as documented, not Makevar.win.  And your output 
does not correspond to the file you showed ....

2) Use .a, not .lib (which is for MSVC).

3) I suspect your 64-bit library is broken.  That's not an R issue, not 
do we know anthing about it.
