Otherwise it will work wrong if arguments contain quoted field separators (e.g. spaces).

#! /bin/sh ./prog --RTS ${1+"$@"}

The longer specification above should work with whatever /bin/sh is around, whether it's Solaris /sbin/sh, FreeBSD's sh, general Linux bash, Debian/Ubuntu dash, etc.

Are you referring to some Solaris shell bug? Under POSIX these constructs seem to be equivalent.
