# This page is for maintenance of the lists of CPP symbols that are eventually
# included in error.c (‘errno’ values: E*) and posix.c (signal names: SIG*),
# in the funcs scm_init_{error,posix}, respectively.
#
# The lists (files cpp-{E,SIG}.syms) are not included verbatim, but processed
# (via pattern rule ‘.syms.c’ below) so that each CPP symbol is transformed to
# fragment of #ifdef'd C code that defines a Scheme variable of the same name.
# The resulting files, cpp-{E,SIG}.c, are the ones #include:d.
#
# To maintain the (source) lists of symbols, we use a GCC-specific feature
# to list all symbols #define:d when expanding <{errno,signal}.h>, grep
# the output for {E,SIG}*, massage the result into a usable form, and
# construct a union of the current and new symbols.  This is written to
# files cpp-{E,SIG}.syms.NEW for review.  If things look ok, you can then
# "mv foo.NEW foo" and commit.  Generating the foo.NEW files and showing
# an informative message is the job of targets chknew-{E,SIG}.

# For each line in foo.syms, transform:
#	SYMBOL
# to:
#	#ifdef SYMBOL
#	scm_c_define ("SYMBOL", scm_from_int (SYMBOL));
#	#endif
# writing output to foo.c.  We use a while-read loop instead of a
# one-line sed script because some seds (e.g., FreeBSD) don't read
# '\n' as a newline (like GNU sed does).  Sad, but true.
