13.10 guile-tools c2x

See Init Snarfing, for discussion.

Usage: c2x [-o OUTFILE] [CPP-ARGS ...]

Process CPP-ARGS using the C pre-processor and some other programs.
Write output to a file named OUTFILE or to the standard output when no
OUTFILE has been specified or when OUTFILE is "-".  CPP-ARGS should
include an input filename.

If there are errors during processing, delete OUTFILE and exit with
non-zero status.

During snarfing, the pre-processor macro SCM_MAGIC_SNARFER is defined.
Also, c2x passes "-I GUILE-INCLUDE-DIR" to the pre-processor, where
GUILE-INCLUDE-DIR is the directory Guile's header files are installed.
(You can display this value with the command "guile-tools guile-config
info includedir".)

If env var CPP is set, use its value instead of the C pre-processor
determined at Guile configure-time.  (You can display this value with
the command "guile-tools guile-config acsubst CPP".)
