egcs-1.0 -frepo problem

["Dr. Andreas Stuebinger" <andreas dot stuebinger at mchp dot siemens dot de>]

Hi,

I have a problem with the appended code snippet. As it is it will compile
with gcc-2.7.2 with included repo patch. However, this is not true for
egcs-1.0. Using egcs-1.0 without -frepo is ok, on using it with -frepo
I have to define USE_EXPLICIT_TEMPLATE to get this explicit template.

My system: Linux i586 RedHat 4.1, binutils-2.8.1.0.1-1, libc-5.4.36-1

Thanks,
	Andreas
