[Frama-c-discuss] Unknows Pragma

That's easy, if by "understand" you mean "ignore":
grep them out at pre-processing (after pre-processing,
in case these pragmas are found inside include files).

Use the option:

-cpp-command "gcc -C -E -I. - < %1  | grep -v pragma\ LINK_INFO > %2"

in addition to what you were already doing.

You may find that the option -cpp-command does not
handle the tokens %1 and %2 as documented.
That's an unfortunate bug. But since you are already setting
yourself up for compiling Frama-C from sources with
your exotic target architecture, it won't be too much additional
trouble to apply the following patch :
