# ===========================================================================

# ===========================================================================
#
# SYNOPSIS
#
# AX_PERL_EXT_FLAGS([CFLAGS-VARIABLE], [LDFLAGS-VARIABLE], [EXTRA-MODULES])
# AX_PERL_EXT_CFLAGS([CFLAGS-VARIABLE])
# AX_PERL_EXT_LDFLAGS([LDFLAGS-VARIABLE], [EXTRA-MODULES])
#
# DESCRIPTION
#
# Fetches the linker flags and C compiler flags for compiling and linking
# programs that embed a Perl interpreter. If the EXTRA-MODULES argument is
# submitted, it is a space separated list of extra modules to link. The
# flags will be stored in the provided variables.
#
# Examples:
#
# AX_PERL_EXT_FLAGS([PERLXS_CFLAGS], [PERLXS_LDFLAGS])
# AC_SUBST([PERLXS_CFLAGS])
# AC_SUBST([PERLXS_LDFLAGS])
#
# AX_PERL_EXT_CFLAGS([PERLXS_CFLAGS])
# AC_SUBST([PERLXS_CFLAGS])
#
# AX_PERL_EXT_LDFLAGS([PERLXS_LDFLAGS], [-std Socket])
