In order to build crtstuff.c, I need to ensure the headers in target/h/wrn/coreip are also searched. Of course, that can be done similar to how wrn/coreip gets manually added for libgcc, e.g. by adding CRTSTUFF_T_CFLAGS += -I$(WIND_BASE)/target/h -I$(WIND_BASE)/target/h/wrn/coreip But without target/h/wrn/coreip in the default search path, all user-code that include <unistd.h> (crtstuff.c just being one such example) will have to manually add an -isystem flag adding the wrn/coreip directory: unistd.h include ioLib.h, which has #include "net/uio.h" and that header is found in target/h/wrn/coreip. In other words, the VxWorks system headers (at least for VxWorks 5.5) are written in a way that assumes wrn/coreip is in the search path, so I think it makes sense to have that by default. It will change the search order for existing setups that pass -I.../target/h/wrn/coreip (without -nostdinc), since that flag will now be ignored. I can't know whether that will break anything, but I do believe it makes sense to have the defaults actually usable without expecting all invocations to add -I/-isystem flags. From-SVN: r263689 |

README
This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
