I have uninstalled GPC package and removed the
/usr/lib/gcc-lib/i686-pc-cygwin/3.3.3/ directory so that now there is not
any reference to 3.3.3 version of GCC (not in the registry not on the
disk).

After this I have tried new builds of CERNLIB with 3.4.4-1 and also in
this case there is the warning like this:


----------------------------------------------------
makedepend: warning: ......  (reading /usr/include/sys/unistd.h, line
13): cannot
find include file "stddef.h"
not in /usr/X11R6/include/stddef.h
not in /usr/local/lib/gcc-include/stddef.h
not in /usr/include/stddef.h
not in /usr/include/w32api/stddef.h

not in /usr/lib/gcc-lib/i686-pc-cygwin/3.3.3/include/stddef.h
    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
----------------------------------------------------


From where the reference to /usr/...../3.3.3/.... ?


(Regarding the problems of GPC package there was a post to this mailing
list, after releasing 3.4.4-1, from a user that got them and he was
invited to downgrade to GCC 3.3.3 if he needed to work with GPC.)


Best regards,

    angelo.
