I haven't used binutils-2.8.1 for a long time. It's mean that also 
egcs-1.1.2 were built using binutils-2.9.1 (I don't remeber about last update of 
gcc-2.8.1)

Here is fragment from gcc/auto_host.h where the detected features appear 
(generated by configure) from gcc-2.95.1

/* Define if your assembler supports specifying the maximum number
   of bytes to skip when using the GAS .p2align command. */
#define HAVE_GAS_MAX_SKIP_P2ALIGN 1

/* Define if your assembler supports .balign and .p2align.  */
#define HAVE_GAS_BALIGN_AND_P2ALIGN 1

/* Define if your assembler supports .subsection and .subsection -1 starts
   emitting at the beginning of your section */
/* #undef HAVE_GAS_SUBSECTION_ORDERING */

/* Define if your assembler uses the old HImode fild and fist notation.  */
/* #undef HAVE_GAS_FILDS_FISTS */

The problem with binutils snapshot was that configure defined
	#define HAVE_GAS_FILDS_FISTS 
which made problems with earlier binutils.

I think both 
#define HAVE_GAS_MAX_SKIP_P2ALIGN 1
#define HAVE_GAS_BALIGN_AND_P2ALIGN 1
are not dangerous with binutils-2.8.1

That are all GAS related features detected by configure.
