Looking at the truss output, gcc tries to locate the header in wrong places:

22203:  stat64("/opt/csw/lib/gcc/sparc-sun-solaris2.10/4.6.1/include/iosfwd.gch",
0xFFBFF038) Err#2 ENOENT
22203:  open64("/opt/csw/lib/gcc/sparc-sun-solaris2.10/4.6.1/include/iosfwd",
O_RDONLY|O_NOCTTY) Err#2 ENOENT
22203:  stat64("/opt/csw/gcc4/include/iosfwd.gch", 0xFFBFF038) Err#2 ENOENT
22203:  open64("/opt/csw/gcc4/include/iosfwd", O_RDONLY|O_NOCTTY) Err#2 ENOENT
22203:  stat64("/opt/csw/lib/gcc/sparc-sun-solaris2.10/4.6.1/include-fixed/iosfwd.gch",
0xFFBFF038) Err#2 ENOENT
22203:  open64("/opt/csw/lib/gcc/sparc-sun-solaris2.10/4.6.1/include-fixed/iosfwd",
O_RDONLY|O_NOCTTY) Err#2 ENOENT
22203:  stat64("/usr/include/iosfwd.gch", 0xFFBFF038)   Err#2 ENOENT
22203:  open64("/usr/include/iosfwd", O_RDONLY|O_NOCTTY) Err#2 ENOENT

My theory is that gcc was confused by the explicit --includedir setting.
