Bootstrap fails on i386-pc-solaris2.10

Hi.

This mornings bootstrap failed on my Solaris machine due to the recent
introduction of the various C++ compatibility warnings. Here's the
snippet from the build log where things failed:

/export/home/arth/gnu/gcc-0630/./prev-gcc/xgcc

The build also failed on my sparc-sun-solaris2.10 system.

The mmap()/munmap() calls in these functions are the cause of the
problem.
