Subject: UIUC cleanup for -Wsign-compare compilation warnings.
X-Git-Url: https://git.mxchange.org/?a=commitdiff_plain;h=4eeeaf140c405a352f595838527b9fb57e1bc172;p=flightgear.git

UIUC cleanup for -Wsign-compare compilation warnings.

The string find_first_not_of() and find_first_of() functions return string::npos
if not found, rather than -1.
