Subject: Reserve for OPENSSL_NO_POSIX_IO macro which is to eliminate references
X-Git-Tag: OpenSSL_0_9_8k^2~1732
X-Git-Url: https://git.openssl.org/gitweb/?p=openssl.git;a=commitdiff_plain;h=1715e4885aecd804f22be7ac17afbbae6c154048

Reserve for OPENSSL_NO_POSIX_IO macro which is to eliminate references
to open/read/write/close. First OPENSSL_NO_POSIX_IO target would be
Windows CE.
