Subject: Avoid readline.h -Wstrict-prototype induced failures
X-Git-Tag: 0.31~35
X-Git-Url: https://arthur.barton.de/cgi-bin/gitweb.cgi?p=bup.git;a=commitdiff_plain;h=a8616d0366d3b0f77cdb9e68f2a8142b5a4c28e1;ds=sidebyside

Avoid readline.h -Wstrict-prototype induced failures

On some platforms -Wstrict-prototype is now the default, and readline
includes prototypes like "int foo()" rather than "int foo(void)", so
for now, just suppress those warnings for the readline includes.
