Subject: libcdecl: Use gperf %7bit option for keyword matching.
X-Git-Tag: v1.3~11
X-Git-Url: https://git.draconx.ca/gitweb/cdecl99.git/commitdiff_plain/318e941af5ec3b0622212ba3d2968efd3c961587

libcdecl: Use gperf %7bit option for keyword matching.

The scanner ensures all input to the keyword matching function consists
exclusively of alphanumeric characters, hyphens and underscores.

Since gperf supports only ISO-646 variants it should be safe to enable
7bit mode, which reduces the size of its generated tables substantially.
