Which C standard does MRI use? When I run configure on HP-UX, it seems
to use C89.
I recently ran into an issue compiling the gherkin gem. Seems that the
C code in that gem makes use of C99 features like variable declarations
in the middle of a block, and variable length arrays.
Is it a bug in the gem to be using these features, or a bug in the MRI
configure script to set the CFLAGS such that C89 is selected at compile
