As many tests use pseudo-random generators, you may get differences
in test output.
Basically, there are 2 random generator scemes used :
via rand() function : expected result in stl_test.rand.exp
via lrand48() function : expected result in stl_test.exp.
System-dependent notices:
If you are using STLport on OS390 machine, you should compare with stl_test.ibm390.exp.
Linux libc uses different random generator which doesn't match any of the above. Be prepared.
map1_test : some compilers don't zero-initialize data when builtin-type default constructor called, thus you may see some garbage instead of 0 in the output.
