            Bug ID: 64347
           Summary: constructor priorities are not supported in avr-gcc
           Product: gcc
           Version: 4.9.3
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: cameron at tacklind dot com

In avr-gcc, if you try to add a priority to a constructor function, you get:
"error: constructor priorities are not supported"

Steps to reproduce:

# echo 'void init() __attribute__((constructor(TEST)));' > test.c
# echo 'int main() {return 0;}' >> test.c

Compiles with no errors
# gcc     test.c -D TEST=1000
# avr-gcc test.c -D TEST=

Does not compile
# avr-gcc test.c -D TEST=1000
