R devel - Jan 2014 - CRAN rejects package because of write statement in Fortran

I recently developed an R package to make available a very large legacy
program written in Fortran.  My package has been rejected by CRAN due to
this Write statement with the message "As 'Writing R Extensions'
warns you
against including Fortran I/O, this will not be allowed." 

The issue is that this Write statement does not involve I/O it is inernally
writing an integer to a character which is then placed in an appropriate
message (character string) passed to the error handling function recommened
in writing R extensions rexit(message).  I'm working with a very large
legacy program which was developed over 16 years and I am reluctant to
rewrite the entire error handling sections in R.  I was wondering if anyone
has gotten CRAN to accept a package with a Fortran write statement
converting numbers to characters or if anyone has found another method for
doing type conversion in Fortran without the "write" statement. 
Thanks for
your help

So the best solution I've had just yet for this problem is to convert
numeric
to character in C and bypass the Fortran "Write" in that way. 
Unfortunately
my C is a bit rusty and I'm having trouble getting this to work.  I image in
the C it should look something like:
void F77_SUB(converti)(char *ch_Result, int
i_Int){*ch_Result=sprintf("%d",*a); }

and in the Fortran something like 
call converti(ch_Result,i_Int)

but this is clearly not right any help would be greatly appreciated.
