on a Solaris8 SPARC machine i couldn't compile the X11R6.6 sources with
optimization (-O2). With at least 5 files compilation aborted as follows
(Paned.c is contained in lib/Xaw).
Without optimization the compilation succeeded.
gcc -fpcc-struct-return -c -O2 -I../.. -I../../exports/include -Dsun
-DHAS_WCHAR_H -DHAS_ISW_FUNCS -fpic Paned.c
