Subject: secnet.h: Change bool_t to a C99 _Bool
X-Git-Tag: debian/0.3.2_beta1~20
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ian/git?p=secnet.git;a=commitdiff_plain;h=09aecaa2e38014fcb27d6ca146b5de9bacd0986d

secnet.h: Change bool_t to a C99 _Bool

This will (a) stop misleading readers of the code (b) make it possible
to write code expecting an implicit !! to be applied to assignments to
booleans (c) possibly make secnet smaller or faster.

I don't expect this to produce any functional change, but I haven't
reviewed every bool_t in secnet to check.
