Sorry it was not en error but warning! I could get the same results as in
that website.

cygwin warning:
MS-DOS style path detected: C:/R/etc/x64/Makeconf
Preferred POSIX equivalent is: /cygdrive/c/R/etc/x64/Makeconf
CYGWIN environment variable option "nodosfilewarning" turns off this
warning.
Consult the user's guide for more details about POSIX paths:

Do you think this warning is a problem and should be fixed/can be fixed?
Best,
