<OpenGL/gl3.h> does not exist there and -framework is not a gcc flag,
so the documented build line failed with no hint why. #+macosx picks
the header now, and both build lines are in the file -- pkg-config
carries the flags on either platform, apart from Apple's GL framework,
which has no pkg-config file to carry.
'#+' and '#-' introduce conditional compilation: the form that follows
is kept only when the feature expression is true, and otherwise is read
and thrown away. An expression is a feature name, or and / or / not
of them.
They are read time, not compile time.
Default features are the host's software-version, software-type and
machine-type as CHICKEN reports them, plus what --features flag adds.
1. Look for `compilation', not `compile' among the source
2. Read the file with provided --features from the (compilation ...)
form, then handle resulting file to sexc
compile-to-file returned process-wait's values and main dropped them,
so cc errors were printed, but then main compiler exited 0.
Also cleanup tmp C files when compilation failed.
Implement pub support for enums, and also anonymous enums declared
in-place.
Also give the cdr of a `pub' form the form's own location, so a
error about what follows `pub' can say where it was written
For source-level debug. Add --line-directives option, defaulted to
statement. Disabled when used with -C. Explicit non-none value
overrides disabling when -C is present
Prior to the fix, the Sex code
`(while (!= EOF (= c (getc f))) ...)` expanded wrongly to
`while (EOF != c = getc(f)) { ...`, instead of
`while (EOF != (c = getc(f))) { ...`
Also rename macros to sex-macros, module-system to sex-modules for
clarity, uniformity, and to avoid name clashes with Chicken's
units/modules named "macros" and "modules"
Spent like 10 minutes trying to understand why my fn pointer is being
fucked up in test case. Turned out I was missing return type, and
whole fn pointer type fall through down to defaut case.
