bug#10896: 23.4; --with-crt-dir was required since crt1.0 not found (on *32bit* system)

[ishikawa]

This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your report will be posted to the bug-gnu-emacs@gnu.org mailing list
and the gnu.emacs.bug news group, and at http://debbugs.gnu.org.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug.  If you can, give
a recipe starting from `emacs -Q':

Compilation failed unless --with-crt-dir was specified during configure on a
32 bit system.

downloaded 23.4 and ran configure as below:
./configure --with-x-toolkit=gtk --without-xim

But then during the subsequent make
it failed due to the dependency on /usr/lib/crt1.0 to make temacs.

Upon investigation, the make variable CRT_DIR is set to /usr/lib
in src/Makefile.
And despite the comment that it is used only on amdx86-64 and ibms390x,
somehow it is being used on this 32-bit Debian system.

Quote from src/Makefile:
# Only used by amdx86-64 and ibms390x GNU/Linux.
CRT_DIR=/usr/lib

It is used in STARTFILES which is referenced as target of temacs
STARTFILES = pre-crt0.o $(CRT_DIR)/crt1.o $(CRT_DIR)/crti.o

crt1.0 is not under /usr/lib on my system. I had to search for it myself.
So I bit the bullet and specified --with-crt-dir in configure line as
below. And the compilation succeeded.

./configure --with-x-toolkit=gtk --without-xim
--with-crt-dir=/usr/lib/i386-linux-gnu

However, something is fishy here. Since
this is NOT a 64 bit system, and not ibms390, CRT_DIR should not be used if
I believe the comment in src/Makefile.
In my use of emacs for more than 20 years, I don't think I ever needed
to specify this CRT_DIR via --with-crt-dir on a popular target.
Maybe the logic to set CRT_DIR is a little broken here?
(Or maybe Debian users are very small or that the users of Debian who
compiles his/her emacs are rarity these days.)

FYI, uname -a prints out the following:
Linux debian-vbox-ci 2.6.39-2-686-pae #1 SMP Tue Jul 5 03:48:49 UTC 2011
i686 GNU/Linux

TIA
