[Report] EPICS R3.13.6 build on RH Linux7.3

[Noboru Yamamoto <noboru.yamamoto@kek.jp>]

Hi,

During the compilation of EPICS R3.13.6 base software on Red
Hat Linux 7.3 I encountered a couple of problem.

1) -UDEBUG_PRINT=0 option crashes gcc/cpp.

Makefile.Host in src/ca includes the line:

USR_CFLAGS += -UDEBUG_PRINT=0

This compiler option, -UDEBUG_PRINT=0, crashes gcc on RH
7.3. Acually any option of the form  "-U<macro>=<val>",
crashes gcc.

2) "int" instead of "osiSocklen_t" in
src/cas/io/bsdSocket/casIntfIO.cc.

In the file src/cas/io/bsdSocket/casIntfIO.cc,
a couple of variables are declared as "int" instead of
"osiSocklent_t". This causes "unable to promote "int" to
"socklent_t" " error with gcc on RH7.3.
We can avoid this error by declaring these variables
as osiSocklent_t.
