dnl This macro uses output of cpp -v and expects it to contain text that
|
|||
dnl looks a little bit like this:
|
|||
dnl #include <...> search starts here:
|
|||
dnl /usr/local/include
|
|||
dnl /usr/lib/gcc-lib/i386-redhat-linux/3.2/include
|
|||
dnl /usr/include
|
|||
dnl End of search list.
|
|||
dnl AS_SCRUB_INCLUDE(VAR)
|
|||
dnl example
|
|||
dnl AS_SCRUB_INCLUDE(CFLAGS)
|
|||
dnl will remove all system include dirs from the given CFLAGS
