Subject: winbuild: Use NMake batch-rules for compilation
X-Git-Tag: curl-7_86_0~218
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8a7ecb57e7d03b790ba51953bda6f817f3f66575;p=thirdparty%2Fcurl.git

winbuild: Use NMake batch-rules for compilation

- Invoke cl compiler once for each group of .c files.

This is significantly improves compilation time. For example in my
environment: 40 s --> 20 s.

Prior to this change cl was invoked per .c file.

Closes https://github.com/curl/curl/pull/9512
