[Bug target/39186] Configury incorrect for 64-bit Targets on Solaris

[rob1weld at aol dot com]

------- Comment #2 from rob1weld at aol dot com  2009-02-14 01:19 -------
A quick hack in ../gcc_trunk/libgcc/configure (line 2065) to
add "-m64" to the 'ac_compile' and 'ac_link' lines will allow
the build to proceed through libgcc to libgcov where it then
fails due to an issue unrelated to this Bug.

Once I get the 'Build Path' constructed I'll go back and
make correct patches to the correct files.


> Andrew: the -X86_64 option is not being passed to as which is a bug in the specs.

I am glad I am not the only one who sees there is something needing
fixing in order for all (most) Platforms to compile with a 'similar 
logic method' (to the extent possible). 

I don't like to see parts of the Build getting skipped when they 
could easily work the same as they do on another Platform. A big 
part of Porting is to get a 'similar' program on different Platforms.
Some Software Manufacturers make 'nearly identical versions' on
quite different Platforms will well received results.

I can appreciate that we are not striving for "identical" but we 
ought to avoid having 100 dozen ways of building gcc as a result of 
having a half dozen ways of asking how it is to be built (for
each HTB).

Rob
