Followed by manual, optional trailing text can be used to give more information
in the warning
message(http://gcc.gnu.org/onlinedocs/gcc-3.4.6/cpp/Pragmas.html#Pragmas ->
'#pragma GCC dependency' section). However, proprecessor gives warning messages
when there is optional trailing text. And this occures above certain
version(3.4.6).

Looks like directives.c:parse_include is not handling the
"dependency" case correctly.
