[Bug bootstrap/21646] New: Boostraping with SUN cc leads to: gcc-4.0.0/libcpp/configure[2760]: test: argument expected

["andreas at florath dot net" <gcc-bugzilla at gcc dot gnu dot org>]

Hello!

Bootstraping the gcc-4.0.0 leads to a error message:
/tmp/gcc-4.0.0/libcpp/configure[2760]: test: argument expected

As far as I see in the line
  if test $GCC = yes; then
the var GCC is not set. It is set in line 2145, but in case of a non gcc
compiler, it is evaluated to an empty string.
  GCC=`test $ac_compiler_gnu = yes && echo yes`

Note 1: Maybe this is a problem with autoconf / automake.

Note 2: As far as I can see there is no functional impact: the 'test' is
evaluated to 'false' which is exactly what is needed at this point.

Note 3: Maybe a bugfix is:
  GCC=`test $ac_compiler_gnu = yes && echo yes || echo no`

Best regards

Andreas Florath
