Subject: random numbers on linux
X-Git-Tag: MOVE2GIT~1915
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=fc40ccd7d252bb9549ea02f385d87fca6b1d6d31;p=nethack

random numbers on linux
Switch the default Linux build behavior to use random instead of lrand48,
since lrand48 exhibits some obviously non-random behavior.  random() has
been in glibc for a long time.  Even if no other changes are made to
nethack's random number generator, this will improve the Linux behavior.
