The GCC 4.5.2, 4.7.3, and 4.8.2 packages do not automatically generate header files in the include-fixed GCC install directory. You might see compiler error messages when building applications that include header files that are not ANSI compliant.
Workaround: To generate the compliant versions of the affected header files, type the following commands:
# for script in /usr/gcc/4.*/lib/gcc/*-solaris2.11/4.*/install-tools/mkheaders ; do
> ${script}
> done
