Harald,
I've looked at the problem. The -Wall option will set the -Wnonstd-intrinsic
option. This flag appears to trigger a warning when used with -pedantic.
It does not trigger a warning if you use it with just -std=f95.
troutmask:sgk[254] gfc4x -std=f95 -Wnonstd-intrinsics -o z iargc.f90
/home/sgk/tmp/ccaTswTS.o(.text+0x55): In function `MAIN__':
: undefined reference to `iargc_'
collect2: ld returned 1 exit status
which by now looks familiar to you.
With "-std=f95 -fall-intrinsic -Wall"., gfortran added iargc to the
list of intrinsics and set -Wnonstd-intrinsics to trigger a warning.
However, the -std=f95 was telling gfc_notify_std to convert the
warning to an error.
I have a patch that will turn this back into a warning. Will this
make you happy?
