The Testsuite gcc.log shows many "getconf: Invalid argument 
(_NPROCESSORS_ONLN)" errors. Here is one example:

PASS: gcc.c-torture/execute/builtins/20010124-1.c execution,  -O0 -flto 
Executing on host: /usr/share/src/lto_build/gcc/xgcc

getconf: Invalid argument (_NPROCESSORS_ONLN)


/usr/share/src/lto_build/gcc/ltrans-driver[99]: [: argument expected


output is:
getconf: Invalid argument (_NPROCESSORS_ONLN)


/usr/share/src/lto_build/gcc/ltrans-driver[99]: [: argument expected


FAIL: gcc.c-torture/execute/builtins/20010124-1.c compilation,  -O0 -fwhopr 
UNRESOLVED: gcc.c-torture/execute/builtins/20010124-1.c execution,  -O0 -fwhopr 


On Solaris if you execute this, you get this:

# /usr/bin/getconf _NPROCESSORS_ONLN
getconf: Invalid argument (_NPROCESSORS_ONLN)

# /usr/xpg4/bin/getconf _NPROCESSORS_ONLN 
getconf: Invalid argument (_NPROCESSORS_ONLN)


But, if you execute this, you get this:

# /bin/ksh93 -c getconf | grep NPROCESSORS_ONLN
NPROCESSORS_ONLN=1

# /bin/ksh93 -c "getconf NPROCESSORS_ONLN"
1


The last result is probably what is wanted.
