Re: 64 bit ABI issue on Solaris

[Stefan Schaeckeler <schaecsn%gmx.net@localhost>]

Anyone having luck with compiling lang/gcc44 on Solaris with ABI=64?

It looks like that the first built gcc is 64-bit. Then, gcc compiles itself. 
This bootstrapped compiler consists of 32-bit object files. To make matters 
worse, the bootstrapped compiler does not link into a binary, because required 
external libs such as libgmp are 64-bit.

Kirk:   Analysis, Mr. Spock?
Spock:  Captain, it doesn't appear in the symbol table.
Kirk:   Then it's of external origin?
Spock:  Affirmative.
Kirk:   Mr. Sulu, go to pass two.
Sulu:   Aye aye, sir, going to pass two.
