Someone (who shall remain nameless since he replied off-list ;-) suggested
maybe sed.  Unfortunately, putting in sed-4.0.7 didn't fix my problem.

So I decided to try and compare the glob.s files from Solaris and HP-UX.

Here are the snipits around the definition of glob64:

Solaris 5.8:

        .asciz  "."
        .section        ".text"
        .align 4
        .stabs  "*glob64:F(0,1)",36,0,368,glob64
        .stabs  "pattern:P(1,1)=*(1,2)=k(0,2)",64,0,364,19
        .stabs  "flags:P(0,1)",64,0,365,25
        .stabs  "errfunc:P(1,3)=*(1,4)=f(0,1)",64,0,366,26
        .stabs  "pglob:P(1,5)=*(37,2)",64,0,367,27
        .global glob64
        .type   glob64, #function
        .proc   04
glob64:
        .stabn 68,0,368,.LLM1-glob64
.LLM1:
        !#PROLOGUE# 0
        save    %sp, -320, %sp
        !#PROLOGUE# 1
        .stabn 68,0,375,.LLM2-glob64
.LLM2:
.LLBB2:
        subcc   %g0, %i0, %g0
        subx    %g0, -1, %o5
        subcc   %g0, %i3, %g0
        .stabn 68,0,375,.LLM3-glob64
.LLM3:


HP-UX B.10.20:

        .word   P%collated_compare
        .SPACE $TEXT$
        .SUBSPA $CODE$

        .align 4
        .NSUBSPA $CODE$,QUAD=0,ALIGN=8,ACCESS=44,CODE_ONLY
        .stabs  "*glob64:F1",36,0,368,glob64
        .stabs  "pattern:P150",64,0,364,8
        .stabs  "flags:P1",64,0,365,10
        .stabs  "errfunc:P293=*294=f1",64,0,366,16
        .stabs  "pglob:P295=*281",64,0,367,13
        .EXPORT glob64,ENTRY,PRIV_LEV=3,ARGW0=GR,ARGW1=GR,ARGW2=GR,ARGW3=GR,RTNVAL=GR
        .stabs  "/media/gnu/make-3.80/glob/glob.c",132,0,0,L$text0005
L$text0005
        .stabn 68,0,368,0
glob64
        .PROC
        .CALLINFO FRAME=320,CALLS,SAVE_RP,SAVE_SP,ENTRY_GR=18
        .ENTRY
        stw %r2,-20(%r30)
        copy %r3,%r1
        .stabn 68,0,375,L$M17-*glob64
L$M17:
L$BB0011
        comiclr,= 0,%r23,%r0
        comiclr,<> 0,%r26,%r19
        ldi 1,%r19
        .stabn 68,0,368,L$M18-*glob64
L$M18:


The more I looked at this, the more it seemed like all that stabn and stabs stuff
was for -g debugging, so I tried recompiling "make" with 'make CFLAGS="-O2"' and
it worked.  But that seems to imply something buggy in GCC itself.

Should I go over and report this or is someone already watching this list for
compiler bugs?
