Thanks for this text. Yes it is correct. Except for two details:
- "... C preprocessor symbols to nonzero values"
I would write "... C preprocessor symbols to 1"
since there is no point in using other values than 1.
- "(e.g. with address@hidden)"
I would omit that, because in larger projects it's more appropriate
to define these through AM_CPPFLAGS in some Makefile.am.
I wish the list of libraries that support this mechanism was not hard-coded.
Do you have an idea for making it extensible?
