Subject: lz_*.c: Use UINT32_MAX for default max_match_len
X-Git-Tag: v1.7.2~64
X-Git-Url: https://wimlib.net/git/?p=wimlib;a=commitdiff_plain;h=f18e3243f913fa48aef3a8cbdad5444cece68cf2

lz_*.c: Use UINT32_MAX for default max_match_len

This avoids max_match_len < min_match_len on extremely small windows.
