Autoconf/automake scripts

[joel.bertrand+binutils@systella.fr]

	Hello,

	I'm working on a 6809/6309/63F09 gcc port. I have copied git tree on a
local server to do some modifications in binutils tree. I have added
some .c and .h (tc-*, opcodes...) and done some modifications in main
configure.ac (I have rebuilt with autoconf 2.72, 2.69 procuded faulty
script). All others configure.ac were rebuilt with autoconf 2.69 and
automake 1.18.

	Now, I'm trying to configure sources and configure scripts return an
error I don't understand.

	If I understand, configure script in gas subdirectory aborts with error.

	Of course, test program cannot be compiled:

| }

	I suppose I have done a mistake but I'm unable to fix it. Help will be
welcome.

	Best regards,
