I don't know if the problem is in gnulib's gl_POSIX_SHELL macro or if xzgrep does something that isn't in POSIX. The workaround adds a special case for Solaris: if /usr/xpg4/bin/sh exists and gl_cv_posix_shell wasn't overriden on the configure command line, use that shell for xzgrep and other scripts. That shell is known to work and exists on most Solaris systems.
