Some points for portability improvements:

1. C++ style comments in C source for ecpg ( // comment )
2. compiler finds wrong include file extern.h in ecpg/lib/descriptor.c
from
include path instead of workdir (rename it ?)
3. fe-connect getsockopt takes a socklen_t as fifth arg not int (use
SOCKET_SIZE_TYPE instead)
4. char vs unsigned char in psql calls to libpq
5. empty define that results in an empty but terminated line ( ; )

Now for all but point 3 I can supply changes to the
compiler flags, to make the compiler less pedantic.
Or is someone interested in the complications ?

in the meantime can someone apply the attached patch ?
