From: Richard Levitte Date: Sat, 30 Jan 2016 01:17:05 +0000 (+0100) Subject: Configure et al: treat C defines separately X-Git-Tag: OpenSSL_1_1_0-pre3~142 X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=bcb1977b7f4186b5551d83839286bc02991c2ad3;p=oweals%2Fopenssl.git Configure et al: treat C defines separately With some compilers, C macros are defined differently on the command line than on Unix. It could be that the flad to define them isn't -D, it could also be that they need to be grouped together and not be mixed in with the other compiler flags (that's how it's done on VMS, for example). On Unix family platform configurations, we can continue to have macro definitions mixed in with the rest of the flags, so the changes in Configurations/*.conf are kept to an absolute minimum.
