./.clean now removes symlinks. Experimental rules for using "pcc" on Solaris x86 were added. C-dependencies on AIX are now extracted using "cc -M -qsyntaxonly". As the new Intel 64 bit strcpy() implementation does not work correctly with overlapping strings, smake now includes a ovstrcpy() function to avoid related problems. Smake now supports $(EMPTY): target names. A minor bug in the makefile parser was fixed. The bug caused targets that appeared directly after an otherwise empty line that started with a TAB character to be ignored.
