visual studio 2014 test failures

From https://ci.appveyor.com/project/Mapbox/node-srs/build/1.0.11/job/erhhc66r9j5g5ax4#L710.

It looks like the data files are not being loaded correctly when osr is compiled with visual studio 2014.

noticing that if I build locally with:

npm install --build-from-source --msvs_version=2013 --toolset=v140

Then all tests pass (note: this is using the pre-built node.exe, which of course is bad).

hmm, all tests pass locally for me too, even with visual studio 2014 compiled node:

..\v0.10.33-nodecpp11\Release\node.exe node_modules\mocha\bin\mocha

Okay, after actually clearing the .node-gyp directory and re-installing using --dist-url I can trigger the problem.

npm install --build-from-source --msvs_version=2013 --toolset=v140 --dist-url=https://s3.amazonaws.com/mapbox/node-cpp11 --target=0.10.33
..\v0.10.33-nodecpp11\Release\node.exe node_modules\mocha\bin\mocha

Tests all still pass with this build if I just run the tests with npm test (which uses the pre-built node.js).

Noting that srs.parse('+init=epsg:4326'); works while srs.parse('EPSG:4326'); or srs.parse('epsg:4326'); fail which seems to indicate a problem loading the data files from the GDAL_DATA environment variable.

After much debugging I've found that getenv is failing right here:

node-srs/deps/osr/src/cpl_conv.cpp

Line 1569 in f4e2b25

pszResult = getenv( pszKey );

and null is returned rather than the correct path to GDAL_DATA. The getenv call does work if GDAL_DATA is set in the environment before node.exe starts but does not work when it is set here

node-srs/lib/srs.js

Line 15 in f4e2b25

process.env.GDAL_DATA = path.join(__dirname, 'srs_data');

I've found that node/src/node.cc uses SetEnvironmentVariableW instead of setenv on windows and I've confirmed that this appears to be the mismatch. Calling GetEnvironmentVariableA returns the right value (set in lib/srs.js).

fixed, whew. Will track back later on and try to figure out what is different about visual studio 2014 runtimes where getenv seems to not talk to SetEnvironmentVariable (mapbox/node#1).

gah, also going to impact proj4 as bundled by node-mapnik: https://ci.appveyor.com/project/Mapbox/mapnik-omnivore/build/1.0.175/job/s4yrxm98uvtt66n2#L138

more proper fix landed in #50
