PAC_C_CHECK_COMPILER_OPTION (in confdb/aclocal_cc.m4) should be able to detect that the "-D_POSIX_C_SOURCE=200112L" flag is not accepted by the Solaris compiler, but it does not. The method used (AC_LANG_PROGRAM() in confdb/aclocal_cc.m4:48) uses an empty parameter, the result of which is an empty main that somehow passes the detection. Replacing it with a "hello world" test case will correctly detect the error and remove "-D_POSIX_C_SOURCE=200112L" from the accepted flags. Configure can then complete successfully. Note that compilation in this configuration will still freeze due to a solaris compiler bug. See #2105.
