Subject: Fixed GMXRC so we are not polluting standard shell variables
X-Git-Url: http://biod.pnpi.spb.ru/gitweb/?a=commitdiff_plain;h=a0dca2211d374df796a438a4e1c4941a3a55c8a9;p=alexxy%2Fgromacs.git

Fixed GMXRC so we are not polluting standard shell variables

csh/tcsh is now detected by looking for the lower-case $shell
variable, which seems to work on all recent platforms, instead
of using the 'set' command (which affected $* and $@ in bash).
Fixes #1044.
