Does anyone know who creates COLLECT_GCC_OPTIONS and how I can influence it? I'm using cpp to expand some c code for data-mining, and it magically finds some header files I don't want it to. When I run cpp with the -v option it's clear why - that variable has the information in it. But it's not in my environment, and that symbol, COLLECT_GCC_OPTIONS, is not in the /usr/bin/cpp executable. I do find it in the binary files in /usr/lib/gcc, but the gcc.gnu.org online manual's keyword index doesn't mention COLLECT_GCC_OPTIONS and I don't find a way to search it. There's no information to be found in google about who creates COLLECT_GCC_OPTIONS or why. So any clue will be greatly appreciated. ----------------------------------------------------------------------------------------------------- http://www.creative-telcom-solutions.de
