sparc-sun-solaris2.6 and sparc-sun-solaris2.8
>Description:
[Note: not really "bootstrap" category, but there isn't a fixincludes category?]
The fixincludes for 3.0.3 on sparc-sun-solaris2.6 produces a sys/types.h that is invalid for use on sparc-sun-solaris2.8 (e.g., on sparc-sun-solaris2.8 it needs to typedef blksize_t).  this makes it hard to use the sparc-sun-solaris2.6-built 3.0.3 to build anything that uses, e.g., fcntl.h, on sparc-sun-solaris2.8, including bootstrapping gcc 3.0.3.

this is the error i get:

>How-To-Repeat:
- build and install 3.0.3 on sparc-sun-solaris2.6
- export that directory to a sparc-sun-solaris2.8 host
- try and bootstrap 3.0.3 with the 2.6-built 3.0.3.
>Fix:
workaround is to build both 2.6 and 2.8 versions, using Sun's cc to bootstrap
