global/src/peigstubs.c:15:8: error: type specifier missing, defaults to 'int'; ISO C99 and later do not support implicit int [-Wimplicit-int]

[jeffhammond]

Intel 2022.2 compilers are enforcing C99, which breaks GA.

Solution

#if ENABLE_PEIGS
#   if ENABLE_F77
#       define gai_diag_       F77_FUNC_(gai_diag,GAI_DIAG)
#       define gai_diag_std_   F77_FUNC_(gai_diag_std,GAI_DIAG_STD)
#       define gai_diag_reuse_ F77_FUNC_(gai_diag_reuse,GAI_DIAG_REUSE)
extern void gai_diag_(Integer*,Integer*,Integer*,DoublePrecision*);
extern void gai_diag_std_(Integer*,Integer*,DoublePrecision*);
extern void gai_diag_reuse_(Integer*,Integer*,Integer*,Integer*,DoublePrecision*);
#   else
#   endif
#else
#endif
