AC_CHECK_DECLS defines the config.h.in variable automatically. If you
want to use AC_CHECK_DECL, yes, you have to use a construct like you
mentioned.
Thank you very much.
what about <math.h>?
how do I have <math.h> included during the check for signgam without
having to define [ACTION-IF-FOUND] and [ACTION-IF-NOT-FOUND] myself?
- Macro: AC_CHECK_DECLS (SYMBOLS, [ACTION-IF-FOUND],
[ACTION-IF-NOT-FOUND], [INCLUDES = `default-includes'])
For each of the SYMBOLS (_comma_-separated list), define
`HAVE_DECL_SYMBOL' (in all capitals) to `1' if SYMBOL is declared,
otherwise to `0'. If ACTION-IF-NOT-FOUND is given, it is
additional shell code to execute when one of the function
... and so on ...
Oh, if you meant to avoid supplying ACTION-IF-FOUND and
ACTION-IF-NOT-FOUND to AC_CHECK_DECLS, just pass them in empty:
AC_CHECK_DECLS (signgam, , , [#include <math.h>])
