unable to build

[quantrpeter]

hi build has error but still producing the hex file, after i burn it to arduino nano, not working. The build error is:

C:\Users\Peter\Desktop\optiboot\optiboot\bootloaders\optiboot\Makefile(682,1): error: recipe for target 'baudcheck' failed
        process_begin: CreateProcess(NULL, bash baudcheck.tmp.sh, ...) failed.
        make (e=2): The system cannot find the file specified.

The baudcheck step of make relies on some utilities that may or may not be present on windows systems. It's mostly pretty-printing of baud rate issues, and the build will work fine without it.

I'll try to do some checking on exactly which packages result in having the full util set.
