about gcc 2.7.2.1

[Hyung Min SEO <HMSEO sec samsung com>]

Thank you Richard and Harley.
I changed /usr/src/linux/arch/alpha/Makefile as following instruction.
"old_gas := yes"
But same error occurred in compiling core_tsunami.c
On system gas version is 2.7(alpha-unknown-linux), using BFD version 2.7.0.2
and gcc version is 2.7.2.1
In core_tsunami.c there is macro assembly code using ldbu, ldwu, stb, stw
which are byte and word instruction, in RedHat 5.2 this macro compiled well,
but RedHat 4.2 not. But I should use RedHat 4.2 to compile MILO.
Because there some libraray conflict with Redhat 5.2.

The bug is in your binutils.

Which you cannot upgrade without upgrading your distribution, 
or being tricky.  The effort for the later is not worth it.

I'm rather surprised the variable $(old_gas) in arch/alpha/Makefile
isn't `y', which should prevent those instructions from being used.
