RE: [avr-gcc-list] Problem building avr-gcc on MinGW

But it is included in the WinAVR distribution.

There is a similar problem in Ada (evaluation of global/static code before
main starts), called elaboration.  gcc-ada includes a special program
(gnatbind) to generate the correct order of calls to the elaboration code
and it also generates the actual main program.  That works already.  Of
course, you usually want to avoid all that fancy stuff when generating
programs that have to fit in 2kB ...
