It looks reasonable to define a getrusage() replacement for native Windows in gnulib. libgfortran (in GCC) has such a replacement already.
First comes a <sys/resource.h> substitute. Reference: http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/sys_resource.h.html 2012-04-12 Bruno Haible <br...@clisp.org> New module 'sys_resource'. * lib/sys_resource.in.h: New file. * m4/sys_resource_h.m4: New file. * modules/sys_resource: New file. * doc/posix-headers/sys_resource.texi: Mention the new module. ============================ lib/sys_resource.in.h ============================ /* Substitute for <sys/resource.h>.
