AsAsm problem

My first try with AsAsm results in the listed error. The problem seems to be to make both AsAsm and GCC use same FPU option. What I also do not quite understand: at this stage a.out has not been created yet, only main.o

asasm -o o.asm s.asm
gcc -c c.main
gcc o.asm o.main

/HostFS::HostFS.$/gcc/!GCC/bin/ld: error: asm.o uses hardware FP, whereas a.out uses software FP
/HostFS::HostFS.$/gcc/!GCC/bin/ld: failed to merge target specific data of file asm.o

Even this gives same error:

asasm -fpu none -o o.asm s.asm
