Subject: (AC_FUNC_MMAP): Cast pointer to
X-Git-Tag: AUTOCONF-2.57b~42
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=efd247863df8df6a1af7b9935573577abc5e355c;p=thirdparty%2Fautoconf.git

(AC_FUNC_MMAP): Cast pointer to
'long', not 'int', for benefit of Sun's recent C++ compilers
(trivial change).  See:
http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
(This really should be 'intptr_t', not 'long', but that would
take more work.)
