# The "-B$libc/lib/" flag is a quick hack to force gcc to link
# against the crt1.o from our own glibc, rather than the one in
# /usr/lib. (This is only an issue when using an `impure'
# compiler/linker, i.e., one that searches /usr/lib and so on.)
#
# Unfortunately, setting -B appears to override the default search
# path. Thus, the gcc-specific "../includes-fixed" directory is
# now longer searched and glibc's <limits.h> header fails to
# compile, because it uses "#include_next <limits.h>" to find the
# limits.h file in ../includes-fixed. To remedy the problem,
# another -idirafter is necessary to add that directory again.
