In this case that would be unlikely to help:  POSIX explicitly allows 
using semicolon as a command separator as an extension.  :-)  (It also 
seems to be historical practice:  configure itself uses this feature.)

Also, various GNU programs have differing notions of what "POSIX mode" 
is.  For example, GNU Awk seems (as far as I have looked so far) to 
actually be POSIX Awk if --posix is given, but bash is well-known for 
still offering GNU extensions even when "POSIX mode" is selected.  Bash 
POSIX mode only guarantees that a script written to POSIX will run, not 
that scripts that run under "bash --posix" will actually also run under 
a POSIX shell.  >-<
