The following lines of code used to compile well using gcc-2.95.x:
#include <sys/stream.h>
#include <queue>
using namespace std;
int main()
{
queue<int> q;
q.push(0);
}
When this is compiled using gcc-3.4.2 the following error is reported:

I think we have a fixincludes regression. The following output is generated
when creating a 2.95.2 sparc-sun-solaris2.8 compiler:

We can see that when the gcc-2.95.2 compiler is created, fixincludes creates a
wrapper for sys/stream.h. When we create a 3.4.2 sparc-sun-solaris2.8 compiler
sys/stream.h is missed during the fixincludes process:
(TARGET_MACHINE='sparc-sun-solaris2.8'; srcdir=`cd ../../src/gcc; ${PWDCMD-pwd}
`; \
SHELL='/bin/sh' ;\
export TARGET_MACHINE srcdir SHELL ; \
/bin/sh ./fixinc.sh `${PWDCMD-pwd}

mv include/limits.h include/syslimits.h; \

fi; \
chmod a+r include/syslimits.h)

I believe we need to include some extra fixincludes for sys/stream.h in the
file gcc/fixinc/inclhack.def when compiling for the solaris platform.
