C unable to confirm this bug on egcs 1.0.1 for i586-pc-sco3.2v5.0.4 robertl

C Subject: g77 crashes compiling Dungeon
C Message-ID: <Pine.OSF.3.91.970823003521.11281A-100000@lynx.dac.neu.edu>
C
C The following small segment of Dungeon (the adventure that became the
C commercial hit Zork) causes an internal error in f771. The platform is
C i586-pc-linux-gnulibc1, the compiler is egcs-ss-970821 (g77-GNU Fortran
C 0.5.21-19970811)

C
C Here's the FORTRAN code, it's basically a single subroutine from subr.f
C in the Dungeon source, slightly altered (the original calls RAN(), which
C doesn't exist in the g77 runtime)
C
C RND - Return a random integer mod n
C
INTEGER FUNCTION RND (N)
IMPLICIT INTEGER (A-Z)
REAL RAND
COMMON /SEED/ RNSEED
RND = RAND(RNSEED)*FLOAT(N)
RETURN
