Subject: Add '-Wall -Werror' to the compile options in the autotools makefile,
X-Git-Url: https://git.distorted.org.uk/u/mdw/putty/commitdiff_plain/b8487fe0a21369fbb9e97616532f8395130bf18c?hp=f0f0ae7f27c50b0bc586d360da17f3cb05e9c467

Add '-Wall -Werror' to the compile options in the autotools makefile,
having just noticed that Makefile.gtk had it and this one doesn't. (Of
course, this being autoconf, we can easily enough make it conditional
on the compiler actually being gcc.)
