12dnl AC_CHECK_DECLS_ONCE like AC_CHECK_DECLS
13dnl AC_REQUIRE([AC_HEADER_STDC]) like AC_HEADER_STDC
14dnl The advantage is that the check for each of the headers/functions/decls
15dnl will be put only once into the 'configure' file. It keeps the size of
16dnl the 'configure' file down, and avoids redundant output when 'configure'
17dnl is run.
18dnl The drawback is that the checks cannot be conditionalized. If you write
19dnl if some_condition; then gl_CHECK_HEADERS(stdlib.h); fi
20dnl inside an AC_DEFUNed function, the gl_CHECK_HEADERS macro call expands to
21dnl empty, and the check will be inserted before the body of the AC_DEFUNed

8dnl in Solaris 2.6, whereas we want binaries built on Solaris 2.5.1 to run
9dnl on Solaris 2.6).
