From: Richard Levitte Date: Fri, 1 Apr 2016 10:36:51 +0000 (+0200) Subject: Force argv to be an array of long pointers on VMS X-Git-Tag: OpenSSL_1_1_0-pre5~175 X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=368058d0a79d2e3b853746b09ca86679a86ac233;p=oweals%2Fopenssl.git Force argv to be an array of long pointers on VMS Reverts commit 087ca80ad83071dde0bb6bc1c28c743caa00eaf8 Instead of battling the odd format of argv given to main() in default P64 mode, tell the compiler to make it an array of 64-bit pointers when compiling in P64 mode. A note is added in NOTES.VMS regarding minimum DEC C version.
