Linux: linux.s / tas.s not found...

Dear PostgreSQL gurus,

with the current CVSup sources, I came across an error
message during the configure step. Using my personal
configure template, linux-elf-libc6, I stumbled into an
error message saying that .../tas.s could not be linked.

To get rid of the message, I had to change the configure
file:
--- snip, snip ---
*** 5258,5265 ****
EOF

cat >> $CONFIG_STATUS <<EOF
! ac_sources="backend/port/tas/${os}.s backend/port/dynloader/${os}.c backend/port/dynloader/${os}.h include/port/${os}.h makefiles/Makefile.${os}"
! ac_dests="backend/port/tas.s backend/port/dynloader.c include/dynloader.h include/os.h Makefile.port"
EOF

cat >> $CONFIG_STATUS <<\EOF
--- 5261,5269 ----
EOF

cat >> $CONFIG_STATUS <<EOF
! ac_sources="backend/port/dynloader/${os}.c backend/port/dynloader/${os}.h include/port/${os}.h makefiles/Makefile.${os}"
! ac_dests="backend/port/dynloader.c include/dynloader.h include/os.h Makefile.port"
EOF

cat >> $CONFIG_STATUS <<\EOF
--- snip, snip ---

BTW: my template for Linux-GNU-GLIBC-2.x (aka libc6) looks like this:

--- snip, snip ---
AROPT:crs
CFLAGS:-O2 -m486 -DHAVE_CRYPT_H=1 -DHAVE_UNION_SEMUN=1
SHARED_LIB:-fpic
ALL:
SRCH_INC:/usr/local/include /usr/local/include/ncurses /usr/local/include/readline
SRCH_LIB:/usr/local/lib
USE_LOCALE:yes
DLSUFFIX:.so
YFLAGS:-d
YACC:bison -y
--- snip, snip ---

Best regards,

Ernst
