Hello,

In a recent attempt to build base R3.14.10 on Windows I have come across
a build problem in src\softIoc\. The Makefile uses fullPathName.pl to
create an EPICS_BASE variable which is the full path to the base
installation. This is passed to the build of the softMain.cpp with the
-D flag and used in the code to create a C string.

Unfortunately fullPathName.pl creates a string with backslashes in it
(when expanding the relative path ../../..). The compiler falls over
when it get to compile this string with backslashes (see build output
below).

Strangely enough I have not come across this problem before when I have
build base R3.14.10 under Windows - but I'm now using a new PC with a
fresh installation of the build tools (Same versions as on my old PC
though: Visual Studio .NET 2003, MinGW 5.1.4 for make and perl
(ActiveState) 5.10.0.1003)

When I fun fullPathName.pl manually it always seems to produce paths
will backslashes on my PC.

I suppose a fix can be done either by adding a flag to fullPathName.pl
to force creation of paths with forward slashes - or alternatively force
the src/softIoc/Makefile to always substitute backward with forward
slashes in the string contained in the EPICS_BASE (local) variable(???)

Here is the output of the build of src/softIoc/softMain.cpp:

Has anyone by any chance come across the same problem?
