Yes those are normal and part of various autoconf test. “-V” I think is accepted by PGI compiler (and may be some other) and would allow for identification of such compiler. “-qversion” is for testing if you are using IBM XL C compiler. The other test is for some preprocessor capabilities (I think). Any auto tooled packages using AC_PROG_CC will display the first two when using gcc. I think the later one is from AC_PROG_CPP but it could be something else.
But there is nothing to worry about. configure is testing for stuff and some errors are allowed and expected.
