I had figured out this already, but conffile.lex.c does not exist in the project, it is generated as a part of the lexer output. In particular: $ ls conffile.lex.c ls: cannot access 'conffile.lex.c': No such file or directory $ flex conffile.l $ ls conffile.lex.c conffile.lex.c And this indeed has config.h include after a few C-specific includes. Since this is not a part of the source, there's nothing I can patch in this file. conffile.l has the config.h include present before everything else, and hence I'm not sure where this should be fixed. Did I misunderstand your solution somehow? If not, can you recommend something else? Best, Nilesh
