using AC_CONFIG_HEADERS in configure.ac

[Natanael C. <nat...@gm...>]

Hi,

I'm looking at the issue with building on Alpine Linux (uclibc):
https://sourceforge.net/tracker/?func=detail&aid=3459926&group_id=204462&atid=989708

There are lots of

#if defined(SYS_THAT_HAS_FEATURE) || defined(OTHER_SYS)
&& !defined(SYS_THAT_HASNT)
...
#endif

I wonder if it wouldn't be better to use AC_CONFIG_HEADERS and from
configure script check for the features and then:

#if HAVE_FEATURE_REGARDLESS_SYSTEM
...
#endif

Are there any particular reasons that AC_CONFIG_HEADERS is not used?

Would you accept patches that adds that?

Thanks!
