realpath on mingw-w64

[jeroen]

Trying to build on windows with msys2 (mingw-w64) fails with:

checking for working strtod... yes
checking for atexit... yes
checking for realpath... no
configure: error: The realpath function cannot be found.

From what I understand from this issue, realpath is actually not a standard ansi/posix function and therefore mingw-w64 does not implement it.

This topic seems to have a working version of realpath for windows. Perhaps we could include that within a #ifdef win32 or so?

Working on feature/windows-realpath.

@emcrisostomo You mean that it works already, or that you are working on it? :) Thanks!

Hi @gaborcsardi, you're welcome. It means that I'm working on it on that branch.

Hi MinGW users, would you mind trying to build the feature/windows-realpath branch?

[gaborcsardi]

@emcrisostomo Thanks! It is improving I believe, I get now:

checking whether lstat correctly handles trailing slash... no
checking for modf... yes
checking for regcomp... no
configure: error: The regcomp function cannot be found.
configure: error: ./configure failed for libfswatch

I don't know if msys2 has regcomp.

Maybe it is in glib2, trying now....

Unfortunately not. Anyway, thanks for the fix, that takes us one step closer.
