I get while trying to build:

 cc -Wp,-H256000  -DIN_GCC    -g  -DHAVE_CONFIG_H -DHAIFA  -o genattr \
  genattr.o rtl.o ` case "obstack.o" in ?*) echo obstack.o ;; esac ` ` case "cc -Wp,-H256000"@"alloca.o" in "cc"@?*) echo alloca.o ;; esac ` ` case "" in ?*) echo  ;; esac ` 
 (Bundled) cc: warning 480: The -g option is available only with the C/ANSI C product; ignored.
 /usr/ccs/bin/ld: Unsatisfied symbols:
    alloca (code)
 make[5]: *** [genattr] Error 1
 make[5]: Leaving directory `/export/d0/yotamm/build/egcs/egcs-971023/gcc'
 make[4]: *** [all-gcc] Error 2
 make[4]: Leaving directory `/export/d0/yotamm/build/egcs/egcs-971023'
 make[3]: *** [gcc-compile] Error 2

It seems the configuration/Makefile fail to generate the right
magic shell-case expression so  obstack.o and alloca.o  will be linked.

Any idea?
