This patch fixes the gcc.dg/c99-stdint-5.c and gcc.dg/c99-stdint-6.c excess error failures.
FYI, some of the problems with the c99-stdint tests are related to the stdint.h implementation in use. For example, some types in AVR-Libc's stdint.h are not defined in the way the GCC test suite expects them: AVR-Libc defines most C99 types by means of attribute mode.
