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

15# or
16#    CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM
17# The environment variables CC, GCC, LDFLAGS, LD, with_gnu_ld

20# The set of defined variables is at the end of this script.

22# Known limitations:
23# - On IRIX 6.5 with CC="cc", the run time search patch must not be longer
24#   than 256 bytes, otherwise the compiler driver will dump core. The only
25#   known workaround is to choose shorter directory names for the build
26#   directory and/or the installation directory.
27
28# All known linkers require a `.a' archive for static linking (except MSVC,
29# which needs '.lib').
