version: egcs-19981206 & egcs cvs current
   host: i386-linux
 config: --target=sh-hms

GCC encounters an internal compiler error when compiling
floatformat.c of the cross-compiler:

  /home/tm/egcs-19981206/gcc/xgcc -B/home/tm/egcs-19981206/gcc/ 
-B/usr/local/sh-hms/bin/ -c -DHAVE_CONFIG_H -g -O2  -m4-single -I. 
-I./../../../include   floatformat.c -o pic/floatformat.o

make[3]: *** [floatformat.o] Error 1
make[2]: *** [multi-do] Error 1
make[1]: *** [all] Error 2
make: *** [all-target-libiberty] Error 2

This same error is exhibited by both snapshot 19981206 and the
contents of cvs as of about noon today.
