These are from shaderdumps (good thing I have the sha naming in place otherwise
these would have been overwritten ;)
When GLSL is not forced
[require]
GLSL >= 0.00 // this is generated by OpenGL so maybe so

I think this function is the problem:
/**
* Return the string for a glGetString(GL_SHADING_LANGUAGE_VERSION) query.
*/
static const GLubyte *
shading_language_version(struct gl_context *ctx)
{
switch (

OpenGL core spec 4.5 page 4 specifies:
"The core profile of OpenGL 4.5 is also guaranteed to support all previous ver-
sions of the OpenGL Shading Language back to version 1.40. In some implemen-

That would explain why a program gets a zero in return when requesting a shader
language lower than the one hardcoded in comment 11. Which is exactly what
happen in comment 8.
Or at least that seems reasona

I'm probably too tired, but this should work I think except it doesnt.
// Little test program to dump supported shader versions
// compiled like this
// gcc test.c -I/usr/include/GL/ -L/usr/lib/x86_64-lin

Ok so I found the problem. We didn't support compat shaders on GLSL 1.40 only
on GLSL versions higher and lower.
I think the Version == 0 might be a separate issue as per comment 15 and it
would be great

Just confirmed that it works now.
Thanks!
Maybe this should be in stable too?
