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:
gcc -c -DHAVE_CONFIG_H -g -O2 -I. -I/home/dcs/wpc/bullet/incoming/gcc-3.0.3/libiberty/../include  -W -Wall -Wtraditional -pedantic /home/dcs/wpc/bullet/incoming/gcc-3.0.3/libiberty/fdmatch.c

>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

Synopsis: sparc-sun-solaris2.6 built 3.0.3 fails to bootstrap sparc-sun-solaris2.8 3.0.3: header problem

State-Changed-From-To: open->closed
State-Changed-By: rodrigc
State-Changed-When: Fri Feb 22 21:05:24 2002
State-Changed-Why:
    I know that the header files for some basic
     types changed on Solaris 
     between 2.6 and 2.7, and between 2.7 and 2.8.
     
     For this reason, I do not think a version of
     gcc compiled under Solaris 2.6 will
     work under Solaris 2.8, because when you
     built gcc, the configure script made some
     assumptions based on the Solaris 2.6 header files.
     
     I'm not sure what the workaround is at this point.
     
     There is a version of gcc 3.0.3 for
     Solaris 2.8 at 
            http://www.sunfreeware.com.
