Perhaps it is the best, that you look at the patch before offering to the lmbench maintainer.
I should note some things to the patch:
1. It emulates rpc functions by adding a file "lib_cygwin.c" which contains empty rcp_...
functions,
so that the rpc functions are disabled and will not be tested.
2. Because the makefile does not have any platform depending parts, generating lat_rpc.exe is
disabled
3. in scripts/lmbench I have added some ' echo -n "*" ' to enable visible feedback for the
long time execution of some benchmarks.
4. On problem I have recognized is with the "lat_select", it hangs on operation.
5. Because I don't have any compare of lmbench running time on other platforms I can't say if
this is okay. Some benchmarks need several minutes to run, but this may be okay.
Regards
Ralf
