How to make GCC stop on first error

[Francesco Montorsi]

Hi all,
    I wonder if there is some option/flag I can feed to gcc to avoid 
that  it continues compiling my source files after it encounters the 
first error... I've searched in gcc docs without success.

This is very annoying when e.g. the first error is due to not finding a 
required header file: after that gcc goes on and spits out tons of 
errors about missing declarations for those things which are declared in 
  the not-found header file.

btw stopping on the first error is the default behaviour of many other 
compilers (e.g. M$, borland, watcom compilers on win32)...

Thanks,
Francesco
