28# The first argument passed to this file is the canonical host specification,

30# or
31# CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM
32# The environment variables CC, GCC, LDFLAGS, LD, with_gnu_ld
33# should be set by the caller.
34#
35# The set of defined variables is at the end of this script.
36
37# Known limitations:
38# - On IRIX 6.5 with CC="cc", the run time search patch must not be longer
39# than 256 bytes, otherwise the compiler driver will dump core. The only
40# known workaround is to choose shorter directory names for the build
41# directory and/or the installation directory.
42
43# All known linkers require a `.a' archive for static linking (except M$VC,
44# which needs '.lib').
