# common rules for compilation of bison parser generator generated files.
#
# this file is automatically included if BISON is set
#
# Variables:
#
# srcdir    ... source directory.
# CC        ... path of GNU C compiler
# BISON     ... The path of the bison binary.
# BISONFLAGS... Flags to pass to bison
# YSOURCES  ... list of *.y files to be processed by bison
# ABI_CFLAGS... ABI-specific CFLAGS, determined by common-compile.mk
# EXT_CFLAGS... pkg-config CFLAGS, determined by common-compile.mk
# INCLUDES  ... list of optional include directories
# CFLAGS    ... C options like -Wall -g -O2
