By the way, proper ANSI C is as portable as any shell script. And proper ANSI C with POSIX threads will run threaded on any POSIX platform.

PCC(1) General Commands Manual PCC(1)
NAME
pcc - APE C compiler driver
SYNOPSIS
pcc [ option ... ] [ name ... ]
DESCRIPTION
Pcc compiles and loads C programs, using APE (ANSI C/POSIX) include files and libraries. Named files ending with .c are preprocessed with
cpp(1), then compiled with one of the compilers described in 2c(1), as specified by the environment variable $objtype. The object files
are then loaded using one of the loaders described in 2l(1). The options are:
-o out Place loader output in file out instead of the default 2.out, v.out, etc.
-P Omit the compilation and loading phases; leave the result of preprocessing name.c in name.i.
-c Omit the loading phase.
-p Insert profiling code into the executable output.
-w Print compiler warning messages.
-B Don't complain about functions used without ANSI function prototypes.
-v Echo the preprocessing, compiling, and loading commands before they are executed.
-Dname=def
-Dname Define the name to the preprocessor, as if by If no definition is given, the name is defined as
-Uname Undefine the name to the preprocessor, as if by
-Idir files whose names do not begin with are always sought first in the directory of the file argument, then in directories named in
-I options, then in /$objtype/include/ape.
-N Don't optimize compiled code.
-S Print an assembly language version of the object code on standard output.
-a Instead of compiling, print on standard output acid functions (see acid(1)) for examining structures declared in the source
files.
-aa Like -a except that functions for structures declared in included header files are omitted.
The APE environment contains all of the include files and library routines specified in the ANSI C standard (X3.159-1989), as well as those
specified in the IEEE Portable Operating System Interface standard (POSIX, 1003.1-1990, ISO 9945-1). In order to access the POSIX rou-
tines, source programs should define the preprocessor constant _POSIX_SOURCE.
FILES
/sys/include/ape
directory for machine-independent #include files.
/$objtype/include/ape
directory for machine-dependent #include files.
/$objtype/lib/ape/libap.a
ANSI C/POSIX library.
SEE ALSO

SOURCE
/sys/src/cmd/pcc.c
BUGS
The locale manipulation functions are minimal. Signal functions and terminal characteristic handlers are only minimally implemented. Link
always fails, because Plan 9 doesn't support multiple links to a file. The functions related to setting effective user and group ids can-
not be implemented because the concept doesn't exist in Plan 9.
