# Compilation environments.
#
# Each compilation environment is declared using the keyword "env", like
# this:
#
# env | <name> | <std> | <defs>
#
# <name> is just a symbolic name for environment.
# <std> indicates either c89 or c99, i.e. which C standard to compile
# under. This infuences choice of compiler and switches.
# <defs> is a list of CPP style -D or -U flags to define C preprocessor
# symbols.
#
# Groups of compilation environments can be named, using the "env_group"
# keyword (this can also be used to create aliases):
#
# env_group | <name> | <envs>
#
# <name> is a name for the group or alias
# <envs> is a whitespace separated list of previously declared environments
# or environment groups (or aliases).
