When I try to build and compile my code, autoconf is creating the configure
file that does the following:
----------------------
# Compile and link our simple test program by passing a flag (argument
# 1 to this macro) to the Fortran compiler in order to get
# "verbose" output that we can then parse for the Fortran linker
# flags.
ac_save_FCFLAGS=$FCFLAGS
FCFLAGS="$FCFLAGS $ac_cv_prog_fc_v"
eval "set x $ac_link"
shift
$as_echo "$as_me:${as_lineno-$LINENO}: $*" >&5
# gfortran 4.3 outputs lines setting COLLECT_GCC_OPTIONS, COMPILER_PATH,
# LIBRARY_PATH; skip all such settings.
ac_fc_v_output=`eval $ac_link 5>&1 2>&1 |
sed '/^Driving:/d; /^Configured with:/d;
'"/^[_$as_cr_Letters][_$as_cr_alnum]*=/d"`
$as_echo "$ac_fc_v_output" >&5
FCFLAGS=$ac_save_FCFLAGS
-----------------------
so when the space is seen, a blank seems to get assigned.
