Bug#401607: gcc-4.1: -m32 does not link
Package: gcc-4.1
Version: 4.1.1-20
Severity: important
I tried to compile a small test-program for 32 bit and got these
results:
bash> gcc-4.1 -m32 hello.c
/usr/bin/ld: warning: i386:x86-64 architecture of input file
`/usr/lib/gcc/x86_64-linux-gnu/4.1.2/../../../crt1.o' is incompatible

There is definetly something wrong with the configuration for 32bit.
I run the same command with the -v paramater:
gcc-4.1 -v -m32 hello.c
Using built-in specs.

So the switch to 32bit was more or less half successful.
