# Below, we strip out all but preprocessor directives.
# We have to take care of situations like
# #if defined(FOO) BAR /* comment line 1
# more comment lines */
# If we just delete text starting from the '/*' to the end of line, we will
# screw up cases like
# #if defined(FOO) /* comment */ \
# && defined(BAR) /* comment */ \
# && defined(BAZ) /* comment */ \
# etc.
# Also, in lines like
# #defined FOO(a,b) a/**/b
# the comment may be important and so needs to be retained.
# This code processes the single-line comments first; it assumes there is
# at most one straightforward comment per continued preprocessor line,
# replacing each non-empty comment (and its surrounding white space) by a
# single space. (sed only has a greedy '*' quantifier, so this doesn't
# work right if there are multiple comments per line, and strings can look
# like comments to it; both are unlikely in a preprocessor statement.) Any
# continuation line is joined, and the process repeated on the enlarged
# line as long as there are continuations. At the end, if there are any
# comments remaining, they are either completely empty or are like the
# first situation. The latter are just deleted by first deleting to the
# end of line (including preceding white space) things that start with '/*'
# and the next char isn't a '*'; then things that start with '/**', but the
# next char isn't a '/'. (Subsequent lines of the comment are irrelevant
# and get dropped.) At the end, we unjoin very long lines to avoid
# preprocessor limitations
