Solaris 9
>Description:
Under SOlaris 9, when trying to use any precompiled header, gcc/g++ bails out with a "had to relocate PCH"-error message.
This is because in the mmap-call in gt_pch_restore(), the MAP_FIXED falg is missing, causing Solaris to return a different address from the specified one.
>How-To-Repeat:
Try to include a file whre a .pch-file exists, too.
>Fix:
Use this patch. One might have to check for solaris, though, since I don't know if MAP_FIXED is a generic mmap option.
