darling-libxml2/SAX.c
Daniel Veillard 56a4cb8c4d Huge cleanup, I switched to compile with
-Wall -g -O -ansi -pedantic -W -Wunused -Wimplicit
-Wreturn-type -Wswitch -Wcomment -Wtrigraphs -Wformat
-Wchar-subscripts -Wuninitialized -Wparentheses -Wshadow
-Wpointer-arith -Wcast-align -Wwrite-strings -Waggregate-return
-Wstrict-prototypes -Wmissing-prototypes -Wnested-externs -Winline
- HTMLparser.[ch] HTMLtree.c SAX.c debugXML.c encoding.[ch]
  encoding.h entities.c error.c list.[ch] nanoftp.c
  nanohttp.c parser.[ch] parserInternals.[ch] testHTML.c
  testSAX.c testURI.c testXPath.c tree.[ch] uri.c
  valid.[ch] xinclude.c xmlIO.[ch] xmllint.c xmlmemory.c
  xpath.c xpathInternals.h xpointer.[ch] example/gjobread.c:
  Cleanup, staticfied a number of non-exported functions,
  detected and cleaned up a dozen of problem found this way,
  avoided a lot of public function name/typedef/system names clashes
- doc/xml.html: updated
- configure.in: switched private flags to the really pedantic ones.
