The problem here is that the GNU-specific option

     -std=gnu99

was specified on the command line, regardless of the brand
of the compiler.  Apparently, the Sun C compiler
can make sense of '-st' and is left with '-d=gnu99'.
Classic culture shock between different compilers.

What ECL's configure should do (if it can) is to supply the
option -std=gnu99 only when it is sure that the C compiler is
from GNU.  E.g. somewhere in configure.in

case $GCC in
   yes) ecl_cflags="-std=gnu99 $ecl_flags"
esac

AC_SUBST(ecl_cflags)

where ecl_cflags is the ECL's shell variable that accumulates appropriates
C compiler flags at configure time.
