------- Comment #1 from kargl at gcc dot gnu dot org 2007-09-17 19:22 ------- I would strongly discourage adding this feature. A long time ago, either Paul Brook or Steven Bosscher and I exchanged email about the use of environmental variables to control various aspects of gfortran. In the end, I recall that we agreed a proliferation of environmental variables could lead to a maintenance nightmare.
But, as usual if someone implements the feature, I won't stand in the way. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=33456
