# This is an alternate setup hook for gcc-wrapper that uses the -I flag to
|
|
# add include search paths instead of -isystem. We need this for some packages
|
|
# because -isystem can change the search order specified by prior -I flags.
|
|
# Changing the search order can point gcc to the wrong package's headers.
|
|
# The -I flag will never change the order of prior flags.
