Description:
Running BUILD/compile-pentium-debug-max in ~/mysql-6.0-bugteam ...
expr: syntax error

How to repeat:
run BUILD/whateverYourPlatform

gcc --version
gcc (SUSE Linux) 4.3.1 20080425 (prerelease) [gcc-4_3-branch revision 134659]

"^.*gcc" in

cc_verno=`echo $cc_ver | sed -e 's/^.*gcc/gcc/g; s/[^0-9. ]//g;        s/^ *//
g; s/ .*//g'`

matches all the way to the *second* occurrence of gcc in version string

version-string on apple is
i686-apple-darwin9-gcc-4.0.1 (GCC) 4.0.1 (Apple Inc. build 5465)

Suggested fix:
can't just "^.*?gcc" since ? is a GNU extension, so make it "^[^ ]*gcc"

  Bug#36519: check-cpu fails with gcc 4.3.1
  
  sed-regex got confused when substring "gcc" occurred
  more than once in "gcc --version"

no longer seeing this issue; this ticket to be re-opened if bug shows again;
closing for now as to not waste review time : )
