[doc] Fix typos in the manual.

Tested 'make html info pdf'.  OK for trunk?

Note that objc.texi had a couple of typos in code snippets
(unsigneld and typdef).

Thanks,
Ralf

Fix typos in the manual.

2010-12-19  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

	* gcc/doc/extend.texi (Function Attributes, Volatiles):
	Fix typos.
	* gcc/doc/install.texi (Prerequisites, Specific): Likewise.
	* gcc/doc/invoke.texi (C Dialect Options, Debugging Options)
	(Optimize Options, i386 and x86-64 Options, MicroBlaze Options)
	(RS/6000 and PowerPC Options, RX Options, Code Gen Options):
	Likewise.
	* gcc/doc/objc.texi (Method signatures)
	(Fast enumeration protocol): Likewise.
	* gcc/doc/tm.texi.in (Run-time Target, Register Arguments)
	(Scheduling, Macros for Initialization, Misc): Likewise.
	* gcc/doc/tm.texi: Renerate.
