# This Makefile fragment (since dpkg 1.16.1) defines the following host
# variables:
#
# ASFLAGS: flags for the host assembler (since 1.21.0).
# CFLAGS: flags for the host C compiler.
# CPPFLAGS: flags for the host C preprocessor.
# CXXFLAGS: flags for the host C++ compiler.
# OBJCFLAGS: flags for the host Objective C compiler.
# OBJCXXFLAGS: flags for the host Objective C++ compiler.
# DFLAGS: flags for the host D compiler.
# FFLAGS: flags for the host Fortran 77 compiler.
# FCFLAGS: flags for the host Fortran 9x compiler.
# LDFLAGS: flags for the host linker.
#
# And the following variables for the build tools (since dpkg 1.22.1):
#
# ASFLAGS_FOR_BUILD: flags for the build assembler.
# CFLAGS_FOR_BUILD: flags for the build C compiler.
# CPPFLAGS_FOR_BUILD: flags for the build C preprocessor.
# CXXFLAGS_FOR_BUILD: flags for the build C++ compiler.
# OBJCFLAGS_FOR_BUILD: flags for the build Objective C compiler.
# OBJCXXFLAGS_FOR_BUILD: flags for the build Objective C++ compiler.
# DFLAGS_FOR_BUILD: flags for the build D compiler.
# FFLAGS_FOR_BUILD: flags for the build Fortran 77 compiler.
# FCFLAGS_FOR_BUILD: flags for the build Fortran 9x compiler.
# LDFLAGS_FOR_BUILD: flags for the build linker.
#
# You can also export them in the environment by setting
# DPKG_EXPORT_BUILDFLAGS to a non-empty value.
#
# This list is kept in sync with the default set of flags returned
# by dpkg-buildflags.
