[PATCH,gfortran] Fix for PR 17941

[Steve Kargl <sgk at troutmask dot apl dot washington dot edu>]

The attached patch fixes PR 17941.  The attached program
is a test program suitable for inclusion in the gfortran
testsuite.

Briefly, gfortran could not deal with spaces between an
uniary plus/minus sign in a complex constant.  That is,
"complex, parameter :: c = (-   1.0,   +  2)" would invoke
an error.

This patch addresses 2 problems.  First, the parsing of the
complex constant did not account for the space.  Second, 
mpfr_set_str() does not like spaces in its input string.

Bubblestrapped and regression tested on i386-*-freebsd6.0

       * arith.c: Include stdlib.h and string.h
       (gfc_convert_real): Use alloca and strlen; account for whitespace.
       * primary.c (match_const_complex_part): Account for whitespace
