SYSCONFDIR: config.h vs. AM_CFLAGS

[ibr at ata dot cs dot hun dot edu dot tr]

Hello,

I'm using SYSCONFDIR in one of my C source files. Currently I pass it
through the following definition:

AM_CFLAGS = ... -DSYSCONFDIR=\"@sysconfdir@\"

This is cluttering the gcc command line, so I want to define it in
config.h. However, I can't figure out how to use it, since autoheader
says that acconfig.h is deprecated, and both config.h.in and config.h
are auto-generated. Is defining everything on the command line really
the best and intended way to do that?

Thanks in advance,
Baurzhan.
