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

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