System: SunOS sic.twinsun.com 5.8 Generic_108528-16 sun4u sparc SUNW,UltraSPARC-IIi-Engine
Architecture: sun4

	
host: sparc-sun-solaris2.8
build: sparc-sun-solaris2.8
target: sparc-sun-solaris2.8
configured with: ../gcc-3.2/configure --disable-nls --enable-languages=c,c++ --prefix=/tmp/prefix --with-system-zlib
>Description:
	The "g++" command creates an executable that does not run due to
	a run-time link path problem.
>How-To-Repeat:
	$ echo 'int main (void) { return 0; }' >test.cc
	$ g++ test.cc
	$ ./a.out
	ld.so.1: ./a.out: fatal: libstdc++.so.5: open failed: No such file or directory
	Killed
	$ ldd a.out
		libstdc++.so.5 =>	 (file not found)
		libm.so.1 =>	 /usr/lib/libm.so.1
		libgcc_s.so.1 =>	 /usr/lib/libgcc_s.so.1

		libdl.so.1 =>	 /usr/lib/libdl.so.1

>Fix:
	g++ automatically appends -L options to the collect2 command, to
	help the linker find libstdc++.so.5 at link-time.  It should also
	append -R options, so that the dynamic linker can find it too.

	A workaround is to use "g++ -static".
