The described problem is only seen if I compile binutils with gcc-4.4.x or
gcc-trunk and one of this two is in the PATH.

If I call the windres wrapper executable in the bintuils directory I get
$ ./windres -v
Tried
`/home/rainer/software/build/i686-pc-cygwin/gcc-4.4.1/binutils/binutils/./.libs/gcc.exe'
Using `gcc -E -xc -DRC_INVOKED  -'
Using popen to read preprocessor output
gcc: error trying to exec 'cc1': execvp: No such file or directory
/home/rainer/software/build/i686-pc-cygwin/gcc-4.4.1/binutils/binutils/./.libs/windres:
preprocessing failed.

If I call windres executable in the binutils/.libs directory instaed I get
$ .libs/windres.exe -v
Tried `.libs/gcc.exe'
Using `gcc -E -xc -DRC_INVOKED  -'
Using popen to read preprocessor output

So that seems to be ok.

My conclusion is that there's a more weired problem which only appears with
gcc-4.4x or gcc-trunk and I don't have an idea how to approach this.
