# COMPILER INFORMATION
#
# These variables give information on the compiler to be used to install
# the release.  CC gives the compiler. CCOPTS and LIBOPTS give any target
# specific options required by the build, and are set by this script.  It
# is recommended that any extra flags which the user requires are made
# part of the definition of CC, so CC="gcc -O" would install using gcc
# in optimising mode.  TCCOPTS controls the extra configuration options
# required when bootstrapping the system using tcc.
#
# To install the bootstrapped compiler, install first using cc or gcc.
# Then remove the work directory (OBJ_DIR), change the compiler to tcc,
# and install again.  Bootstrapping is recommended (all our testing is
# on the bootstrapped compiler).
#
# SYS_INCLUDES gives a list of include file directories to be searched
# when building the TDF API libraries.
#
# STRIP may be set to "strip" in order to ensure that the installed
# executables are stripped.
#
# RANLIB is used on those platforms on which system libraries need to be
# ranlib-ed.
#
# EXEC_SUFFIX is used on those platforms where executable names need to
# have a particular suffix, for example it may be set to ".exe".
