Hello. I am new to autoconf, and I am sorry if dumb question. Could you explain, how the AC_USE_SYSTEM_EXTENSIONS macro works ? It looks like the macro blindly defines all known 'extensions' symbols, regardless of target system. Say, on my OpenSolaris 10 this macro defines STDC_HEADERS, _ALL_SOURCE, _GNU_SOURCE and _TANDEM_SOURCE, which aren't used in system headers. However, many applications, say, libnet, python, ImageMagick uses these symbols in their development headers. I could suppose, that if someone uses 'libnet' for development and AC_USE_SYSTEM_EXTENSIONS as part of configuration, he gets incorrect 'libnet' headers. So, which idea is behind the AC_USE_SYSTEM_EXTENSIONS macro, and how to use it ?
