Of course.  That was really an elliptic reference to this pr:

David O'Brien replied:
"We don't yet support building 32-bit apps on a a 64-bit system. 
We only barely support *running* them at this point. " 
and then closed the pr.

It's rather amusing that known defects don't deserve open 
problem reports, and you can't really expect people to stop
submitting reports if you keep marking as closed the previous 
reports without fixing them.

===original contents of pr===
"Though /usr/bin/ld reports that it can make elf_i386_fbsd,
cc -m32 simple-c-file.c does not properly build

gcc does not translate -m32 to mean that ld must be envoked
with /usr/lib32 bits instead of /usr/lib/crt1.o
/usr/lib/crti.o /usr/lib/crtbegin.o

also mistakenly gives: -dynamic-linker /libexec/
and -L/usr/lib instead of -dynamic-linker
/libexec/ and -L/usr/lib32


Following simple test program (main.c):
#include <stdio.h>
int main() { printf("Hello world\n"); return 0; }
