[iwan at irs dot phy dot nrc dot ca]

The following simple program is rejected by gfortran
(commandline: gfortran junk.f)
with this error message:

 In file junk.f:6

     *      1.4)
             1
Error: Period required in format string at (1)
 In file junk.f:4

      write(6,10) x
               1
Error: FORMAT label 10 at (1) not defined

c------------------------------ begin test program
      program junk
      real x
      read(5,*) x
      write(6,10) x
 10                                                            format(g1
     *      1.4)
      end
c------------------------------- end test program

The compilation succeeds with gcc 3.3.x and earlier
The compilation also succeeds if one removes the 
blanks beetwen the line continuation and 1.4 in the format statement.

Created an attachment (id=10339)
 --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=10339&action=view)
A one line change that seems to fix Bug 24268 

Have tested the change on several large fortran 77 source files.
I'm not sure if a similar change is needed for case '+' in 
format_lex().

This is now fixed for the specific test case. 4.1 and 4.2 are in sync.  I plan
to go back and review for other possible cases of whitespace.  Just want to
keep this synchronized.
