Using zsh in gcc compilation

["David Gómez" <david@xxxxxxxxxxxx>]

Hi all,

I cannot get to compile successfully gcc 3.2 using zsh as my main shell. I'm
sure the problem is caused by zsh becaused i tried to compile with bash and the
problem goes away.

I hope maybe some of you could give some hints about what is causing this
problem. This is the situation:

/bin/sh is pointing to the zsh binary

zsh options that are activated:

nohistbeep
histexpiredupsfirst
nomultios
rmstarsilent
shinstdin
shwordsplit

These are the last lines of the compilation, when a parse error is given when
the libgcc_s_on is going to be linked:

This error seems to happens because an additional '-on' is added to the xgcc
line and the output doesn't go to standard output, so we have an empty
libgcc.map, but i have no idea which zsh feature could be causing this.

Thanks,
