Code not compiling since 19d5486 due to concatenate operators in macros

Hi all,
(resending patch as it looks that it was stuck in administration queue
of this ML...)

I noticed this morning that ODBC does not compile correctly since
commit 19d5486 due to some macros using concatenate operators used
with CORR_STRCPY and CORR_VALCPY in psqlodbc.c and connection.c.

In the case of CORR_VALCPY the macro simply needs to copy a field one
by one, and for CORR_STRCPY only a string is copied, so concatenate
operators are not necessary IMO. Please find a patch fixing that by
removing the unnecessary operators.
Regards,
